Re: How can I pass the URL of the page I am on?

[Trimbach]

... and if you want to find out the URL of the webpage that triggered your CGI in the first all you have to do is:

$referrer=$ENV{'HTTP_REFERER'};

and that's that. No CGI.pm, no forms, no nothin'.

And not reliable!
• Referer may be missing (stripped by security software and/or firewalls)
• Referer may be wrong (some browsers blow it on the spec)
• Referer is trivially faked
The big clue is, how can you rely on a variable with an incorrectly spelled name!
