I have this testing setup with the following sites SiteA SiteB SiteC SiteA has a link to SiteB. SiteB redirects(in some way) to SiteC. On SiteC this php code Code: echo $_SERVER['HTTP_REFERER']; shows SiteB as the referer, also firefox 'view page info' on SiteC shows SiteB as the referer. I know this has been a contentious issue and at this point of my testing I only need to know whether this means the server really records SiteB as the referer. I don't know whether this would have any effects on the results, but sites A,B and C in my testing are on the same domain. So I am hoping(not sure) if SiteA and SiteC are on different domains and servers then the SiteC server should not have a clue about SiteA. PS: This is not about cookie stuffing, although I am also wondering whether the method would deal with the referer issue while cookie stuffing. At this point it is for cloaking purposes only, where I would like the merchant to see the referer as a site on my domain not yahoo, youtube, metacafe, myspace or whatever for that matter.
