Hi, I need to develop a webpage with an IFrame and I need to know the external URL/URI where the user is on the webpege with the IFrame. At the begin I was thinking to use the "PHProxy" solution, but PHProxy is not totally reliable. It fails with some URL's/URI's. My questions: What other solution can I use to track the page that the visitor is browsing on the IFrame? "Squid" will help me in this type of task? Give some clues on how to achieve this. I have google but I can't find much information on how to deal with this case. Best Regards,
