Re: Referrer variable
But a word of caution, the referer is not a required header! It is
encouraged "as a convenience to the back end" but not a required
attribute of a request. We were bitten by this at tribe.net as I was
relying on referer being there all the time which isn't true for all
browsers. It turns out that we had a case of IE6 on Windows XP (or
something like that) where the referer was not in fact being passed in.

Re: Referrer variable
Posted by Tony Oslund <ao...@bevcomm.net>.
This is correct, the HTTP_REFERER is not guaranteed to be in the header.
If you search for REFERER in the following doc it points this out.
http://httpd.apache.org/docs/misc/FAQ.html. (Thank you Robert Fuess at
Digital Point Forums).
Ilan wanted to know how to access this value so I didn't want to stop him.
Depending upon his environment and what he is doing it may or may not give
him the desired result. He seemed pretty confident and direct so I assumed
that he knew about its limitations.
By the way, this is not a Turbine limitation, but apparantly (based on
various comments) can be caused by the browser (as you stated), proxy
servers, ssl, dhtml, and numerous other real (or imagined) culprits ;-).
