Squid gives Error while posting a comments

I configured Squid 2.6 on FC5. It is working fine and I am able to
browse websites. Today I encountered with a strange problem. I noticed
that whenever I submit comments on news items or reports, squid takes
long time and finally gives an error.I received the following error.
********************************************

The following error was encountered:

The system returned:
