Hi, There are 2 squids running behind 2 different firewalls and 2 diffrent internet connections (same isp, different network ranges). Users report that they get problems viewing the site. When i look at that site through 2 proxies and with different browsers i get different results (and its changing) , especially i get some errors about the web site codes from ie but when i switch the proxy through ie i see diffent results. Sometimes i get the error 400 and after i clear the cache of the browser and request the site it turns back. 1 firewall has IPS running 1 not but couldnt find anything at the ips logs either. The web sites owners didnt answer to my questions yet. What do you recommend to anaylyze and fix the issue? Other sites are viewed well through bot of them. Regards
