While perhaps unlikely in common users it is also possible to prevent your browser from sending the referrer. IIRC, the referrer can also get mangled when passing through HTTPS (although I don't remember on which side, HTTP-HTTPS or HTTPS-HTTP or both) Matt On Thu, Jan 12, 2012 at 1:11 AM, Ross McKay ro...@zeta.org.au wrote: On Wed, 11 Jan 2012 21:27:58 -0800, Haluk Karamete wrote: [...] Notice: Undefined index: HTTP_REFERER in D:\Hosting\5291100\html\blueprint\bp_library.php on line 16 die; [...] But I'm still curious, what configuration am I missing so that http_referer is treated like that?
