Quick notes on SSI's
CGI stands for "Common Gateway Interface," a
fancy name meaning computer programs running on the webserver that can be invoked from a
www page at the browser. The "bin" part alludes to the binary executables that
result from compiled or assembled programs. It is a bit misleading because cgi's can also
be Unix shell scripts or interpreted languages like Perl. CGI scripts need to be saved in
ASCII format and uploaded to your server's cgi-bin in ASCII or text format. This is very
important.
We don't provide free support for CGI scripts which we
did not install on our server. So if you are not already familiar with CGI scripting, you
can read a book on the subject or find places on the Internet with CGI scripting
information. There are many good resources for CGI scripts found on the web. The scripts
at Matt's Script Archive found at http://www.worldwidemart.com/scripts/
are very good. Many of our scripts come from here. Another excellent resource is The
CGI Resource Index found at http://www.cgi-perl.com/
-- if you are not an expert, look for scripts that are very well documented and come with
step-by-step instructions.

The following is a simple explanation of
file permissions in Unix. To list the access permissions of a file or directory, telnet to
the server, then:
cd directoryname
to change the directory until you are either
in the directory above the file you are interested in, or above the directory you are
checking.
Type: ls -l filename
and you will see what the current permission settings are
for that file, along with a bunch of other stuff.
Examples of using chmod:
| PEOPLE |
PERMISSIONS |
| u = the file's user (you) |
r = read access |
| g = the file's group |
x = execute access |
| o = others |
w = write access |
| a = the user, the group, and others |
|
To change permissions for a file named filename.cgi, you
need to chmod the file (change mode). For example, when you type this:
chmod u=rwx,g=rx,o=rx filename.cgi
you've given:
read, execute, and write access to the
user (that's you)
read and execute access to the group and
read and execute access to others
Some scripts will tell you to chmod 775 (for example).
Doing the above is the same thing as typing chmod 775. You can use either method with our
Unix servers. To explain:
When using the numeric system, the code for permissions
is as follows:
r = 4 w = 2 x = 1 rwx = 7
The first 7 of the chmod775 tells Unix to change the
user's permissions to rxw (because r=4 + w=2 + x=1 adds up to 7. The second 7 applies to
the group, and the last number 5, refers to others (4+1=5).
When doing an ls -l on the file, telnet always shows the
permissions this way:
-rwxr-xr-x
Ignore the first dash, then break up the above into three
groups of letters. If there's a dash where a letter should be, it means that there is no
permission for those people.
Remember:
the first 3 apply to user, the second 3 apply to group, and the third 3 apply to others.
Some FTP clients support changing permissions in a more
graphical way.
CuteFTP for
Windows has an easy way to change permissions. With CuteFTP, go to the file you want to
change the permissions on, and highlight it. Then right click and select "Change file
attributes" and you will be given a simple graphical interface to change the
permissions of the selected file or directory.
With Fetch,
go to the file you want to change the permissions on, and highlight it. Under the Remote menu, select Change Permissions. A window
will pop up showing the current permissions for the file you highlighted. Click on the
boxes to change permissions as needed.
WS_FTP
accomplishes the same task as above. Just highlight the file you want to check, and
right-click on it. A menu will pop up, then select CHMOD.

Below are solutions to some of the more
common CGI script problems, in question and answer format. You will find a list of proper
permission settings for the scripts we provide at the end.
When I activate my CGI
program, I get back a page that says "Internal Server Error. The server encountered
an internal error or misconfiguration and was unable to complete your request."
This is generally caused by a problem within
the script. Log in via Telnet and test your script in local mode to get a better idea of
what the problem is. To do this, go into the directory in which your script is located,
then execute the script. To execute the script, you can do it two ways:
1) Type "perl myscript.pl" (Perl
being the language interpreter in this case).
2) Or simply type "myscript.pl"
alone. This will work if the first line is well written to indicate the location of Perl.
The first one is useful to see if there are
any errors IN your script. The second one is useful to test if your "calling
line" (the first line of the script) is okay, i.e. if you entered the right location
of Perl.
I am being told
"File Not Found," or "No Such File or Directory."
Upload your Perl or CGI script in ASCII
mode, not binary mode.
When I test my Perl
script in local mode (by Telnet), I have the following error: "Literal @domain now
requires backslash at myscript.pl line 3, within string. Execution of myscript.pl aborted
due to compilation errors."
This is caused by a misinterpretation by
Perl. You see, the "@" sign has a special meaning in Perl; it identifies an
array (a table of elements). Since it cannot find the array named domain, it generates an
error. You should place a backslash (\) before the "@" symbol to tell Perl to
see it as a regular symbol, as in an email address.
I am getting the message
"POST not implemented".
You are probably using the wrong reference
for cgiemail. Use the reference /cgi-bin/cgiemail/mail.txt. Another possibility is that
you are pointing to a cgi-bin script that you have not put in your cgi-bin directory. In
general, this message means that the web server is not recognizing the cgi-bin script you
are calling as a program. It thinks it is a regular text file.
It's saying I don't have
permission to access.
This error message means that you are
missing your index.htm or the default.htm file for FrontPage. Note:files that start with a
"." are hidden files. To see them, type ls -al. If you wish to FTP this file in,
go to the home/yourdomain directory. Again, DO NOT FTP files that are directly related to
your FrontPage website.

This script is one from Matt's Script Archive which we
have installed and preconfigured for your domain. FormMail is a generic www form to email
gateway, which will parse the results of any form and send them to the specified user.
This script has many formatting and operational options, most of which can be specified
through the form (you don't need any programming knowledge or multiple scripts for
multiple forms). This also makes FormMail the perfect system-wise solution for allowing
users form-based user feedback capabilities without the risks of allowing freedom of CGI
access.
There is only one form field that you must have in your
form for FormMail to work correctly. This is the recipient field. Other hidden
configuration fields can also be used to enhance the operation of FormMail on your site.
The action of your form needs to point towards this script and the method must be POST in
capital letters.
Here's an example of the form fields to put in your form:
<FORM METHOD=POST
ACTION="http://yourdomain.com/cgi-bin/formmail.cgi">
<input type=hidden
name="recipient" value="whoever@yourdomain.com">
<input type=hidden
name="subject" value="Order">
<input type=hidden
name="return_link_url" value="http://yourdomain.com/">
<input type=hidden
name="return_link_title" value="Back to Main Page">
The following are descriptions and proper syntax for
fields you can use with FormMail.
Recipient Field
Description: This form field allows you to specify to whom you want your form
results to be mailed. Most likely you will want to configure this option as a hidden form
field with a value equal to that of your email address.
Syntax:
<input type=hidden name="recipient"
value="email@yourdomain.com">
Subject Field
Description: The subject field will allow you to specify the subject that you want
to appear in the email that is sent to you after this form has been filled out. If you do
not have this option turned on, then the script will default to a message subject:
"WWW Form Submission".
Syntax: If you wish to choose what the subject is:
<input type=hidden
name="subject" value="Your Subject">
To allow the user to choose a subject:
<input type=text
name="subject">
Email Field
Description: This form field will allow the user to
specify their return email address. If you want to be able to return email to your user, I
strongly suggest that you include this form field and allow them to fill it in. This will
be put into the From: field of the message you receive. If you want to require an email
address with valid syntax, add this field name to the 'required' field.
Syntax:
<input type=text name="email">
Realname Field
Description: The realname form field will allow the
user to input their real name. This field is useful for identification purposes and will
also be put into the From: line of your message header.
Syntax:
<input type=text name="realname">
Redirect Field
Description: If you want to redirect the user to a
different URL, rather than having them see the default response to the fill-out form, you
can use this hidden variable to send them to a pre-made HTML page.
Syntax: To choose the URL they will end up at:
<input type=hidden name="redirect"
value="http://yourdomain.com/to/file.html">
To allow them to specify a URL they wish to travel to
once the form is filled out:
<input type=text name="redirect">
Required Field
Description: You can require certain fields in your
form to be filled in before the user can successfully submit the form. Simply place all
field names that you want to be mandatory into this field, separated by commas. If the
required fields are not filled in, the user will be notified of what they need to fill in,
and a link back to the form they just submitted will be provided. To use a customized
error page, see 'missing_fields_redirect'
Syntax: If you want to require that they fill in
the email and phone fields in your form, so that you can reach them once you have received
the mail, use the syntax like:
<input type=hidden
name="required" value="email,phone">
Env_report Field
Description: Allows you to have Environment variables included in the email message
you receive after a user has filled out your form. Useful if you want to know what browser
they were using, what domain they were coming from or any other attributes associated with
environment variables. The following is a short list of valid environment variables that
might be useful:
REMOTE_HOST - Sends the
hostname making the request.
REMOTE_ADDR - Sends the IP address of
the remote host.
HTTP_USER_AGENT - The browser the
client is using.
Note: In
our case, both REMOTE_HOST and REMOTE_ADDR are the same, since our servers don't do the
reverse DNS lookup needed to generate the true REMOTE_HOST string.
Syntax: If you wanted to find all the above
variables, you would put the following into your form:
<input type=hidden
name="env_report" value="REMOTE_HOST,REMOTE_ADDR,HTTP_USER_AGENT">
Sort Field
Description: This field allows you to choose the
order in which you want your variables to appear in the email form that FormMail
generates. You can choose to have the field sorted alphabetically or specify a set order
in which you want the fields to appear in your email message. By leaving this field out,
the order will simply default to the order in which the browsers send the information to
the script (which is usually the exact same order as they appeared in the form). When
sorting by a set order of fields, you should include the phrase "order:" as the
first part of your value for the sort field, and then follow that with the field names you
want to be listed in the email message, separated by commas.
Syntax: To sort alphabetically:
<input type=hidden name="sort"
value="alphabetic">
To sort by a set field order:
<input type=hidden name="sort"
value="order:name1,name2,etc...">
Print_config Field
Description: print_config allows you to specify which
of the config variables you would like to have printed in your email message. By default,
no config fields are printed to your email. This is because the important form fields,
like email, subject, etc. are included in the header of the message. However, some users
want this option so they can have these fields printed in the body of the message. The
config fields that you want to have printed should be in the value attribute of your input
tag separated by commas.
Syntax: If you want to print the email and subject
fields in the body of your message, you would place the following form tag:
<input type=hidden
name="print config" value="email, subject">
Print_blank_fields Field
Description: print_blank_fields allows you to request that all form fields are
printed in the return HTML, regardless of whether or not they were filled in. FormMail
defaults to turning this off, so that unused form fields aren't emailed.
Syntax:
<input type=hidden
name="print_blank_fields" value="1">
Title Field
Description: This form field allows you to specify
the title and header that will appear on the resulting page if you do not specify a
redirect URL.
Syntax: If you wanted a title of 'Feedback Form
Results':
<input type=hidden name="title"
value="Feedback Form Results">
Return_link_url Field
Description: This field allows you to specify a URL
that will appear, as return_link_title, on the following report page. This field will not
be used if you have the redirect field set, but it is useful if you allow the user to
receive the report on the following page, but want to offer them a way to get back to your
main page.
Syntax:
<input type=hidden name="return_link_url"
value="http://yourdomain.com/index.htm">
Return_link_title
Description: This is the title that will be used to link the user back to the page
you specify with return_link_url. The two fields will be shown on the resulting form page
as:
Back to Main Page
Syntax:
<input type=hidden name="return_link_title"
value="Back to Main Page">

Cgiemail is provided to non-FrontPage accounts. This is
another form processing script, totally different than FormMail, discussed above. It is a
program written in the C language that takes the contents of fill-in boxes on a form and
emails them to a specified location. In addition to the form specification in the .html
file, a mail specification in a .txt file is required to format the resulting email
message.
We provide the cgiemail in the cgi-bin directory of our
server. You need to have an action in your order.htm file to call it. It should look like
this:
<form method=post
action="http://www.yourdomain.com/cgi-bin/cgiemail/order.txt">
Details are provided below. While there are a number of
subsections below this one, they all work together and are meant to be read from start to
finish.
order.htm
Look for a file in your www directory called order.htm. This
is our example form we put on your site that shows how a form should be configured to work
with Cgiemail. Look at it in a browser, and download it to your hard drive using FTP so
you can see how it works. If you've never dealt with HTML forms before, don't worry,
they're easy to create and understand.
The form prompts the user for data which is sent to the
server as simple key-value pairs. Each <input> tag specifies a record. The key is
given by the name attribute, and the value is given by the value attribute.
The type attribute tells the browser what kind of data to expect. Now, try looking
at the example.
Please note that the hidden items are used to transmit
critical info to Cgiemail. They provide the location of the success file, the name of the
person the results should be sent to, and the subject of the form. When making your own
forms, you may want to change the email address in the "required-to" field, and
likely the subject in the "subject" field. The first item tells Cgiemail what to
show the user after successfully completing the form. You can, but don't need to customize
this.
After that come the items that are actually presented to
the user. You'll want to use type=text input items with cgiemail: it's a simple tool. The
size=60 tells the browser how big to make the box. The name=something is required in each
input tag, otherwise the browser wouldn't know how to send the data to the server. The
value=" " attribute is correct in most cases, unless you want a default value in
the form.
Note that if a field begins with required-, cgiemail will
require that the user enter a value for this field. This is particularly useful if you
want to require a user to submit their email address.
When the user presses the Submit button, the data goes to
our machine where cgiemail starts doing something with it. What is does is controlled by
the order.txt file discussed below.
By the way, you can name your HTML form anything you want
to.
order.txt
Now that we have all this data, what do we do with it? Mail
it, of course! But for flexibility, cgiemail requires that you create a mail.txt file to
show it what to send. (If you didn't want flexibility you'd use a mailto link.) The
program will read this file, perform substitutions, and pass it to the mail system.
Make sure that you upload mail.txt in ASCII mode. Failure
to upload mail.txt in ASCII mode will generate the message:
"Server Error: The server encountered an internal
error or misconfiguration and was unable to complete your request."
There is already an example order.txt document in the
forms directory in your www directory.
There is nothing special about the name order.txt. Feel
free to call it mail1.txt or form1.mail, or whatever suits you, as long as the form has
the correct name for what you uploaded.
Note: the first several lines are mail headers. You
probably shouldn't change that part or the corresponding parts in your form. In
particular, there must be a To: header or the mail won't go anywhere!
What cgiemail does is simply replace every string that
looks like [key] with the value the user typed into the field with name=key. You can lay
out your form as is best for your users, but lay out your mail.txt as is best for you to
read. You can even insert lots of text to help format the output. Only the [key] parts
will be replaced by cgiemail.
Cgiemail does not report environmental variables like
FormMail, but other than that, it is an excellent program, allowing you more flexibility
in the way you want your data returned by the form.

Normally, any text (such as your credit card number) sent
from your browser to the web server is sent as plain text. This means that a hacker could
potentially intercept (however unlikely) the information sent from your browser and read
it. However, by using the secure server, the information is encrypted before it is sent
from your browser. It would be practically impossible for anyone to decrypt it without
knowing the key. Please use the secure server only when necessary, as when requesting
sensitive information from your visitors.
The domains hosted by our company are housed on a number
of computers and all of them have a different machine name. To find out what machine name
to use for your secure order access calls, check the faq file of your domain at:
http://www.yourdomain.com/faq.html
Each server has its own faq file which is dedicated to
that particular server. Even though you will be putting your form on your own domain, it
must be called through the secure server in order for the form to be secure.
To do this, create your form as usual and put it
somewhere in your www directory. You can put your form anywhere that you want, but for
this example, let's assume the normal URL for your form can be accessed from a browser
with this URL:
http://www.yourdomain.com/signup/secureform.html
To call the form through the secure-order server, you
need to use the following URL to access your pages via the secure server (even though your
form resides on your own domain space): https://machinename/yourdomain/signup/secureform.html
That would be the URL you would put as an <HREF> to
link to your form from whatever page you have your visitors link from. Don't forget the
"s" in "https."
To call scripts in your cgi-bin via the secure
server you should use a URL like this:
https://machinename/cgi-yourdomain/your-cgi.cgi
Special instructions for using
FormMail.cgi with the Secure Server:
If you are using formmail.cgi through the secure server,
you can still place your form anywhere on your webspace that you want, but you MUST use
the following URL as the ACTION of your form: https://machinename/cgi-bin/formmail.cgi
Here's an example of how the first parts of your form
might look:
<FORM METHOD=POST
ACTION="https://machinename/cgi-bin/formmail.cgi">
<input type=hidden
name="recipient" value="whoever@yourdomain.com">
<input type=hidden
name="subject" value="Order">
<input type=hidden
name="return_link_url" value="http://yourdomain.com/">
<input type=hidden
name="return_link_title" value="Back to Main Page">
It is still important that you call your order page
through a secure URL in order to work properly. You must use:
https://machinename/yourdomain/order.htm
If you call formmail.cgi through the secure server, you must also call the order form
through the secure server. Otherwise, a "bad referrer" message will result.

Guestbook allows you to set up your own comments page.
From there, visitors can add entries to your guestbook and they will be displayed with the
most recent at the top and scrolling down, or vice versa. Other options include the
ability to limit HTML in the entry, link to email address with mailto tag, use a log to
log entries, redirect to a different page after signing, emailing whenever a new entry is
added, and much more.
Guestbook is already set up for your use. You can simply
use the following URL to access it: http://yourdomain.com/Guestbook/guestbook.html
If you want to change any of the configuration options,
locate the guestbook.cgi file in your Guestbook directory (inside your www directory).
Download it to your hard drive in ASCII mode, and save it somewhere safe. Create a copy of
the file and give it the same name, then edit the options as specified below. Keep your
backup of the original guestbook.cgi in case you run into problems.
Option 1: $mail
This option will allow you to be notified via an email address when a new entry arrives in
your guestbook. The entry will be mailed to you as a notification. If you want to turn
this variable on you will need to fill in the 2 variables that go along with it:
$recipient - Your email address, so that the mailing
program will know who to mail the entry to.
$mailprog - The location of your sendmail program on your
host machine.
Option 2: $uselog
This will allow you the ability to use the short log feature. It is already turned on so
you will have to change it to 0 if you do not want to use it.
Option 3: $linkmail
Turning this option on will make the address links in your guestbook become hyperlinked.
So instead of simply having (name@some.host) it will put (<a
href="mailto:name@some.host">name@somehost</a> so that anyone can
simply click on the address to email them.
Option 4: $separator
This allows you to choose whether you want guestbook entries to be separated by a
Paragraph Separator <p>, or a Horizontal Rule <hr>. By changing the 0 in the
script to a 1, you will turn on the <hr> separator and turn off the <p>
separator. The 0 option will do the reverse of that; turn on the <p> and turn off
the <hr>.
Option 5: $redirection
By choosing 1 you will enable auto redirection and 0 will return a page to the user
telling them their entry has been received and click here to get back to the guestbook.
Option 6: $entry_order
Set this option to 0 and the newest entries will be added below the rest of the entries.
Keep this option at 1 and the guestbook will add the newest entries at the top.
Option 7: $remote_mail
Many users of the guestbook want a form letter to be automatically sent to the remote user
when they fill in the guestbook. Turning this option on will tell the script to
automatically email any user who leaves an email address. You can specify the contents of
the email message by editing the section of the script that sends email to the remote
user. By default it sends a message that says, "Thank you for adding to my
guestbook." and then shows them their entry. If you should choose to turn this
variable on, you will need to fill in the 2 variables that go along with it:
$recipient - Your email
address so that the mailing program will know who to mail the entry to.
$mailprog - The location of
your sendmail program on your host machine.
Option 8: $allow_html
This option allows you to turn on or off the use of HTML tags by users of your guestbook.
Setting this variable to 1 allows users to embed html tags such as <b> or <H1>
or <a href=" "></a> into your html document. Setting this variable
to 0 will not allow them to use any html syntax in their comments or any other field. You
can still link to their comments or any other field. You can still link to their email
address by turning $link_mail to 1.
There is also the ability for users to add their own URL
and then their name is referenced to their URL in the guestbook.html file. This helps to
eliminate the need for allow_html to be turned on, and lets users point you to a spot that
will tell you more about them. If you want to disable this option, simply delete the
following line from your addguest.html file:
URL: <input type=text name=url
size=50><br>
guestbook.html
This is the file that you will link to that will contain the Guestbook Entries. You may
want to edit the title and heading spaces and customize the look. Do not delete the line
<!--begin--> from this guestbook, or else the script will have no way of knowing
where to begin the editing. The <!--begin--> line is the only necessary line in your
guestbook.html file, but the link to the addguest.html file is also a good idea.

Free-For-All Links page allows you to set up a web page
which your users can then add links to in specified categories. Newest links are added to
the top of each category. A running total of the number of links present as well as the
time when the last link was added is shown at the top of the page. Your preconfigured
Free-For-All Links page is already set up at:
http://www.yourdomain.com/links/links.htm
The only configuration you might want to do is to customize the look of the links.htm
page. Just leave the method and input tags the way they are. If you decide to change the
category names, you must do so in the links.htm document, AS WELL AS the links.pl file in
your cgi-bin.
Back to the Top of this Page
This script is preconfigured for you. There is a
directory in your www directory called "random." Inside that directory is a file
called random.txt. Just download this file to your hard drive and edit it with any random
text you would like placed in an html document. Remember to keep the %% separator between
quotes. You can use any html formatting tags you want to, including <href> tags so
you can configure it as a random link generator. You can put in as many quotes as you
want. Upload the random.txt file to the server in the same location you found it,
remembering to upload it in ASCII or text mode.
The script uses SSI (Server Side Includes) so the page
you want to use random text on must have the .sht, .shtm, or .shtml extension. On your
page, just put this tag wherever you want the random text to appear:
<!--#exec
cgi="/cgi-bin/randomtext.cgi"-->

WWW Board is a threaded World Wide Web discussion forum
and message board, which allows users to post new messages, follow-up to existing ones and
more. It is already preconfigured for you. Just go to
http://www.yourdomain.com/bbs
to post your messages there.
There are several options you might want to configure.
First of all, the index.sht file in the bbs directory can be customized any way you want
as long as you leave the method and input tags the way they are.
Secondly, there are some options contained in the
wwwboard.pl script itself (located in your cgi-bin directory) which you might want to
change, depending on your needs:
$show_faq = 1;
This option allows you to choose whether or not you want to display a link to the FAQ on
every individual message page or not. It defaults to 1 and the link will be put in at the
top of the message along with links to Follow-ups, Post Follow-up and Back to $title.
Setting this to 0 will turn it off, and keeping it at 1 will keep the link. You need to
create a faq.html file and put it inside the bbs directory. The FAQ can contain any
information you want to give your visitors about how the board works, your organization,
types of postings that will be allowed, etc.
$allow_html = 1;
This option lets you choose whether or not you want to allow HTML mark-up in your posts.
If you do not want to allow it, then everything that a user submits that has <>'s
around it will be cut out of the message. Setting this option to 1 will allow HTML in the
posts and you can turn this option off by setting it to 0.
$quote_text = 1;
By keeping this option set to 1, the previous message will be quoted in the follow-up text
input box. The quoted text will have a ':' placed in front of it so you can distinguish
what had been said in the previous posts from what the current poster is trying to get
across. Setting this option to 0 will leave the follow-up text box empty for the new
poster.
$subject_line = 0;
There are three options for the way that you can display the subject line for the user
posting a follow-up. Leaving this option at 0 which is the default value, will put the
previous subject line into the follow-up form and allow users to edit the subject. Setting
this option to 1, however, will quote the subject, but simply display it to the user, not
allowing him or her to edit the subject line. The third and final option can be achieved
by setting the $subject_line variable to 2. If it is set to 2, the subject will not be
quoted and instead the user will be prompted with an empty subject block in their
follow-up subject line.
$use_time = 1;
This option allows you to choose whether or not you want to use the hour:minute:second
time with the day/month/year time on the main page. Day/Month/Year will automatically be
placed on the main wwwboard.html page when a new entry is added, but if you leave this
variable at 1, the hour:minute:second time will also be put there. This is very useful for
message boards that get a lot of posts, but if you would like to save space on your main
page, you can set this to 0, causing the hour:minute:second display not to be added.

Search will look at all your html pages for words you
enter, and return all pages on a list with links. This program is completely configured,
but for Search.cgi to return a response, it needs to be activated. This is done by logging
in via telnet and at the prompt after login type the following command:
chmod +r /www/yourdomain
Now you can access search.cgi with the following URL: http://yourdomain.com/cgi-bin/search.cgi
There is a configuration file called search_define.pl
which accompanies search.cgi and sets up the variables for it. You can customize which
files you want to exclude from searches and also the cosmetics of the search and results
pages.

There is a Single Page Shopping Cart program installed on
the server. You can see what it looks like by going to this URL with your browser:
http://www.yourdomain.com/shop/boutique.html
If you want to customize the shopping cart, (and you will
if you want to sell products using this program), you can visit:
http://virtualpublisher.com/host4u/index.html
The Virtual Publisher Shopping Cart program is
sophisticated and complex. Rather than reprint all their directions here, please go to
their website and download the help files associated with it.

There are 3 different types of page counters you can
place on your pages. The first is a graphical counter which looks like this:

To use this one, put the following tag somewhere on your
page, but change the yourpage.htm to be the address of the actual page you are putting
this counter on. The width=5 part refers to how many digits you want in your counter.
This counter is not as reliable as the others mentioned.
<IMG
SRC="/cgi-bin/nph-count?width=5&link=http://yourdomain/yourpage.htm">
Another page counter you may want to use is the Virtual
Publisher Counter (on qualifying accounts only). It is another graphical counter, but it
will give you all kinds of stats such as time and date of visits, and domains that your
visitors come from. It looks like this:

To put this counter on your page, insert the following
tag somewhere... please note that the line had to be broken up to fit on this page, but
the line should not be broken on your page.
<img
src="http://yourdomain.com/cgi-bin/counter/counter.cgi?
fnam=testcount&viz=yes&isinv=yes&setup=
/home/www/yourdomain/cgi-bin/counter/setup.txt">
Where you see fram=testcount, put in the
name of the page you want to put the counter on instead of the word testcount. The viz=yes part tells the counter script whether your counter should
be invisible or not. If you want the counter to be visible, leave it as yes. If you want
it to be invisible, change it to viz=no.
The isinv=yes part is for whether you want the counter to
be inverted or not. The default as below means that it is inverted (as shown in the
graphic above). If you want it to be a black number against a white background, change it
to isinv=no.
Another great thing about this one is that you can access
the log files for each page you have the counter on, and also reset the count to any
number you want. To see the instruction page, go to
http://yourdomain.com/counter/ with your web browser.
Please be aware that a count file will not be created
until a page is accessed for the first time.
Finally, the simplest kind of page counter is a
text-based counter. It uses SSI so the page you are putting it on must have the .sht,
.shtm, or .shtml extension. It will look like whatever text and size attributes you give
it on your page. The tag looks like this:
<!--#exec
cgi="/cgi-yourdomain/counters/counter.cgi"-->
After you've put the counter on your page, look at
it with your browser. If you don't see the counter the first time, hit reload. Then you
should see the number 1. If you want to change the page count, FTP to your site, and look
in the counters directory in your cgi-bin. There will be a file there with the name of
whatever page you placed this counter on. Just upload a new text file with a new number on
it, and that will be the new count on the page next time you hit reload. Remember to
upload the file in ASCII or text format.

Your domain is capable of supporting use of SSI's,
support is limited to the exec cgi command and in order for the system to process the
include you must save the page with a .shtml or .sht rather than .htm or .html
Sample SSI:
<!--#exec cgi="/cgi-bin/count.cgi"-->
Please note as shown in the example above, the URL
must be relative and not a full call, the following will not work:
<!--#exec
cgi="http://yourdomain.com/cgi-bin/count.cgi"-->
