Does anyone know if I can reliably use the Linux Server Referer to make decissions within a php script ??
I am only interested in arivals on the page from another page within the site.
I have therefore already eliminated the direct arivals.

I am using:

CODE

$referer = $_SERVER['HTTP_REFERER'];

Depending where the visitor came from I am making decissions as to what happens within a page.
However, a thought occurs to me that maybe not all browser etc configurations may leave the Referer footprint.
Anyone shed any light on this please.

Correct, the referer is an optional field in the HTTP request headers, and is turned off by some Internet security packages, so use it, but don't rely on it being populated.

Thanks Chris that's what I suspected.
