Hi Amos, Since we a have numbers of subscribers It is hard for me to identify and visit each subscriber. You see I have another proxy running on version squid-2.6 Stable 3 and we not facing any problem. Do you have any idea how can I solve it on the squid level instead of identifying the clients, and how am I going to fix it. Can you recommend installing the older version 2.6 stable 3 instead?

You need to track down if you can which client is doing this and fix it. Amos -- Please be using Current Stable Squid 2.7.STABLE5 or 3.0.STABLE11 Current Beta Squid 3.1.0.3
