all you have to do is set the ACTION attribute of the
FORM in your HTML code to tell the browser where to
post the form contents.....
example:
<FORM ACTION="http://server.com/cgi/blah.pl" METHOD="POST">
will POST the form contents to "blah.pl"
then, it is up to you to get the information that's
been posted (i highly recomend Deurl.pm by Jenda Krynicky
it's on CPAN somewhere... just search for it)
