hi, i need some serious help! i have a script i got from hotscripts.com that helps you control errordocument handling..
the script works pretty well, execpt that i NEVER know what page the person who fires of my errordocument handler is coming from.
for instance, a person is at my site on the following page:
toocrooked.com/index.html
they click some link that leads to a 404, and my error handler picks it up. the error handler emails me info about the error, for instance the type (404), the requested link (toocrooked.com/nonexistant.html) and the referring page (toocrooked.com/index.html)
...however, i NEVER have EVER never gotten the referring page. i have asked for help about this before on other places, and stupid [expletive deleted]'s always say "oh, someone is blocking the referrer. oh you didnt spell referrer right", and etc. but they are just plain stupid. so thats why im here - i need a real, correct answer.
anyway, heres how the code looks:
.HTACCESS

again, i NEVER get a referer! the code is perfectly correct!! why wont the .HTACCESS file pass the god forsaken referring URL?
better yet, how can i get the HTACCESS to pass a GET variable with the referring URL in it, for instance, instead of calling errorpage.php, how can i get it to call:
errorpage.php?ref=%{REFERER} (or something like that)
