There appears to be a problem with the connection pinning in both versions squid-2.7.stable7 and squid-3.1.0.7. I have some network captures that show the client (IE6) creating multiple TCP connections to the squid proxy and the proxy creating multiple TCP connections to an IIS server. The initial couple of requests are OK but after that the input TCP connection to output TCP connect is broken. The requests are changing output bound TCP connections. This is breaking the NTLM authentication handshake. I can supply my squid configuration files if needed. I do have NTLM authentication enabled in both configurations. I have tcpdump traces for both versions available. In the 3.1 dump summary, note that the client packet 207 is the server packet 210. The server should be on port 37159 and it is on port 37161. Can a developer look at this?
