Hi, When users (using Microsoft or Firefox) tries to a enter into a Fecebook group, the page turns to load too slow until its impossible to load the page. Without proxy it works fine. This is the web console output from Firefox when I try to enter into a fecbook group: Notice it takes more than 20000ms to load objects. -- [11:00:28.342] GET http://www.facebook.com/ajax/home/generic.php?ajaxpipe=1&ajaxpipe_token=AXjEe5Q2ya55Qi_-&sidecol=true&path=%2Fgroups%2Fgalerialaurahaber%2F&sk=group_274387729331843&key=group_274387729331843&endpoint=%2Fajax%2Fhome%2Fgeneric.php&__user=750553986&__a=1&__adt=2 -- [11:00:51.473] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=34&partition=96&clientid=47fb592d&cb=fp8p&idle=7&state=active [HTTP/1.0 200 OK 40579ms] -- [11:01:32.073] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=34&partition=96&clientid=47fb592d&cb=hyoe&idle=2&state=active [HTTP/1.0 200 OK 40033ms] -- [11:01:37.747] POST http://www.facebook.com/ajax/chat/buddy_list.php -- [11:02:12.119] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=34&partition=96&clientid=47fb592d&cb=mddb&idle=4&state=active [HTTP/1.0 200 OK 17063ms] -- [11:02:29.198] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=35&partition=96&clientid=47fb592d&cb=kh9s&idle=22&state=active [HTTP/1.0 200 OK 3531ms] [11:02:33.019] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=36&partition=96&clientid=47fb592d&cb=klfo&idle=25&state=active [HTTP/1.0 200 OK 10688ms] -- [11:02:43.733] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=37&partition=96&clientid=47fb592d&cb=lpiq&idle=36&state=active [HTTP/1.0 200 OK 40720ms] -- [11:03:24.488] GET http://5-ect.channel.facebook.com/pull?channel=p_750553986&seq=37&partition=96&clientid=47fb592d&cb=4yb5&idle=77 Any Idea ?
