Sorry for the other mail chain. it was opened accidentally yesterday. Thanks for the response. please find the required data below. http://pastebin.com/Abs3QmMe --> cache.log http://pastebin.com/eS94BHHu --> TCP Dump. I was able to see the site logged in access.log with http code 504, Gateway Timed Out. so i thought the packets are sent to squid. For your kind attention, i have not installed Squid 3.1.10 from YUM. I have Compiled and installed from the source with the following options. http://pastebin.com/jFhzd3qj Thanks, Ganesh J On Tue, Jul 8, 2014 at 10:44 PM, Nyamul Hassan <nyamul@xxxxxxxxx> wrote: > Ok.
