OK, so I have setup a site here: http://www.thisismyrevenge.com/ There is a frame in the page not visible to the human eye as all it does is link to a PHP file that logs the referrer. I have looked at my log and got this as a result: 2008-11-20 20:43 - IP ADDRESS - Referer: http://www.thisismyrevenge.com/sponsor1.html sponsor1.html is a page that I am iframing which links to another page and then a DMR and then another page blah blah blah. But as you can see there is am ip address there which is not mine, is this my website's server IP address? If so, I take it that your CPA network / AM would be pissed off if your referring ip addresses were all the same? UPDATE: Oops, forgot I had changed ISP today so my IP has changed. A few people from this forum seemed to have clicked on my site now and the referrer is showing blank for them for some reason, anyone know the string to include the browser in the log as well?
