chromatic's regex appears to be picking up the domain rather than the path. Did I miss something?

Heh. chromatic misspelled 'HTTP_REFERER' by spelling 'referrer' correctly :) The beauty of misspelled standards...

I'd use the following regex, so long as you remember that the referrer can be easily spoofed and this isn't being used for security: 

$ENV{HTTP_REFERER} =~ m!^[^:]+://[^/]+/([^?]+)! or die "No path info!"
+;
my $path = $1;

The final [^?]+ strips off the query string. Switch it to .* if you want the query string.

The or die on the regex kicks off if we don't have a path. Obviously, if the referrer is something like "http://www.yahoo.com/", you're going to have a problem. However, I assumed that your referrer would probably have a path appended. You can change that to or some_error_subroutine() if you like.

Alternately, if no path info is acceptable, make sure that $path is set to "" on a regex failure. Otherwise, if anything was already in $1, then that would be assigned to $path and obviously, this is undesirable (thanks to chromatic for pointing that out to me).
