Reasons for Using SSI
SSI is often used to include something into an HTML page. You can insert the
contents of one HTML page into another page. An example of a practical usage
for this would be to include your e-mail address at the bottom of each page.
If you do this as an include, then when your e-mail address changes, you
will only have to update it on one page and not your entire web site.
Another usage is to call cgi scripts into action. Many counters, clocks, and
other scripts are called using SSI. The command used will most likely be
provided in the documentation of
your cgi script.
