In your CGI, you can capture $ENV{HTTP_REFERER} and use it in an href
back to the "previous" page (essentially the page from which they arrived.)
i.e.:
print "<A HREF=\"$ENV{HTTP_REFERER}\">Back to Previous Page</A>";
(correct me if i got anything wrong there, it's been a long night writing
message boards in html)...
What I need to know from anyone who can help is which browsers do and
don't send this information. I know AOL and Netscape's do. It'd
certainly help in a lot of the scripts that we're writing to have it.
Any list somewhere of which browsers support what?
