Greetings, Squid Cache: Version 2.7.STABLE9 Access URL: https://remote.phau.com.au:987/grains/default.aspx With no intervening proxy server, the above site returns an untrusted SSL certificate warning which, once accepted, takes me through to a login dialog. With the proxy server in the chain, squid returns a "Connection to 165.228.126.196 Failed " - the untrusted cert warning page is not returned. The squid logs display the following - 1309240053.271 60029 148.145.157.200 TCP_MISS/504 0 CONNECT remote.phau.com.au:987 - DIRECT/165.228.126.196 - There is nothing displayed in the cache log. The research I've done typically reports as follows (and also that there is little I can do about it save contacting the target servers admin): <snip> This server (squid) did not receive a timely response from an upstream server it accessed to deal with your HTTP request. This usually means that the upstream server is down (no response to the gateway/proxy), rather than that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data. </snip> Could it be the certificate warning which is causing the timeout and if so are there ways to configure squid to deal with it.
