Description

I have set a socket timeout on my request, but I've discovered that the socket timeout is not honored when a proxy is being used and the proxy does not respond to the "CONNECT" command. See the attached stack trace, and note the call in org.apache.http.impl.execchain.MainClientExec.createTunnelToTarget - this is the request that does not timeout. Thanks.

It's trivial to reproduce this by using Fiddler as the proxy, with Fiddler configured to break before requests (Rules->Automatic Breakpoints->Before Requests).
