Hi, The system is using Squid version 3.1.8. I have configured squid to use a url_rewrite_program that redirects users to the company portal sites under certain circumstances. The problem is that the portal sites references external content and the external content URI's are also being re_written. Is there any way for me to determine if a particular uri has a referer? It would be idea if I could determine the referer's domain name, but even just knowing if the uri request has a referer would be helpful. Sincerely, dustfinger.
