Hi Omid, I had exactly the same issue and it bothered me for ages. Tried all the steps that you took but to no avail. Finally I tried upgrading to the latest source code and the problem disappeared. I'm not very technical but I'm guessing it's related to this bug http://bugs.squid-cache.org/show_bug.cgi?id=3528
That is only related to 3.2. The 3.1 series has no Host: verification security.
Daniel -----Original Message----- From: Omid Kosari i have checked everything in this thread . also i have done every tips from http://squidproxy.wordpress.com/2007/06/05/thinsg-to-look-at-if-websites-are-hanging/ http://squidproxy.wordpress.com/2007/06/05/thinsg-to-look-at-if-websites-are-hanging/ but unfortunately some websites does not open through squid. note1: web sites will open if i manually set proxy settings in my browser ( port 3128 ) but when route the traffic to squid ( port 3129 tproxy ) they don't open . note2: squid server can open those websites simply with lynx .
Requests made from the Squid server use the squid server IP as source. They are useful only in eliminating ECN, PMTU, etc issues. They do not test any problems with routing of TPROXY packets.
http://wiki.squid-cache.org/Features/Tproxy4 has quite a laundry list of things to look at and be wary of. The troubleshooting section lists a few ways packets can get lost or connections "hang". Anything marked with a yellow asterisk icon, or a red cross icon may also be relevant to this problem.
note3: i tested with changing mss even below 500 , changing mtu of router interface and squid interface below 1200 , disabling ECN and WSS etc . no success nothing special in log files even with debug level more than 3 . ubuntu 12.04 server LTS 64bit . squid Version 3.1.19 most of websites work fine but few of them have problem
Which ones exactly? it may be something specifically related to them and how squid is attempting to connect.
