what kind of solution are you looking for? if you want to figure out what's generating those queries, check any system that's generating them; that'll hopefully help you locate the problem on all the systems. on your system, you can run wireshark/tshark or tcpdump and capture packets sent to your proxy, and analyze them.

Dear osama,
Salam,

A program tried to use the proxy with a request that is either not HTTP or is part of the HTTP extensions your squid can't handle yet. see cache.log for info on which request method was tried.

Best Regards.

This is in cache.log. What is that mean
