If you use the CGI.pm module, you will find that all of those "CGI environment variables" are made easy to access. For example: `$calling_url = $q->referer();` [download]	[reply] [d/l]

The CGI specification dictates several environmental variables to be set. The complete list of all CGI environmental variables is located here. The variable you are interested in is HTTP_REFERER. In perl it is accessable as. `$ENV{HTTP_REFERER}` [download]	[reply] [d/l]

There's no reliable way to do it. Any answer that lists `$ENV{HTTP_REFERER}` or something derived from it needs a disclaimer that states: It can be trivially faked It can be absent It can be wrong So, beware the clueless attempting to give you clues. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]

I am the one who betrayed the monastry and believes that modules are not good until you are an advanced monk! Try this without using modules: $referer = $ENV{'HTTP_REFERER'}; print $referer; The result will be the refering URL	[reply]
