Your question is difficult to answer, because it could
be interpreted many ways. If what you mean though, is say,
a user hitting http://www.foo.com/, and you want a counter
to get updated, for instance... no cgi script has
apparently been run; the user has hit no buttons...
This can be done with server side includes. You need to
talk to your web server administrator, or if you are that
person, read up on SSI...
