WBR.
Please try 3.0.STABLE20 and confirm that the problem still exists.
There are a few hang and infinite loop errors resolved since *16. Some
rather nasty remote DDoS security issues as well.

OK, thank you for tip. I'll try to use 3.0STABLE20 & post the results on the list immediately. Now I'm looking for the linux http downloader software, that may using CONNECT - for squid testing purposes. Unfortunately - no results as yet :)

I have not tested this, but from a quick check of the code its should work:

  squidclient -m CONNECT -P file host:port

If you create a fake HTTP request and store the request headers in "file" the above should send a CONNECT request for "host:port" to Squid then pass the contents of "file" through the tunnel same as a downloader would.

The only difference from a regular CONNECT is that squidclient will add a Content-Length: header which do not usually go on CONNECT requests due to their unpredictable nature.
