Unless that value is wrong (sometimes), faked (possibly), or stripped
(by a security-conscious user, browser, or gateway).
REFERER is just a hint. Trust it about as far as you can throw
your computer. Laptops don't count. :)

RE: A request's Origins
If you're simply looking for which link they clicked on to bring them to
this particular page/screen; it should be stored in $ENV{HTTP_REFERER}
Also:
my $prev_page = $r->header_in("Referer"); #

A request's Origins
Hello folks, I am trying to find out where (which machine) a request has come from. We have several web servers running on different machines serving different documents, so it is possible to jump servers back and forth. This means that I would have to know what prev->uri was/is and what r->uri was/is. The problem is that if the request object is the original one, not a redirect or ErrorDocument handler r, the r->prev returns undef. Jumping from one server to another is not a redirect (in my case), so r->prev returns undef every time. Any ideas? Also, has any one encountered an error using MLDBM::Sync saving to an NFS mounted file? Appreciate all comments. Thanks in advance -r
