While I am trying HTCP support for squid 3.0 stable 10, I ran into some issues. Hope someone could give me some leads on how to solve it. Here is my setting. I have two Linux running squid, which is compiled with --enable-htcp. One is used as parent for the other. On the parent side (188.168.75.20). I put the following configs: localnet 188.168.0.0/16 htcp_port 4827 htcp_access allow localnet htcp_access deny all On the child side (188.168.77.20), I put the following configs: localcnet 188.168.0.0/16 htcp_port 4827 htcp_access allow localnet htcp_access deny all cache_peer 188.168.75.20 3128 4827 htcp However, whenever I am trying to access any website that is not in the cache of the child, curl returns the following error code: curl: (52) Empty reply from server I hope that I explained it clearly enough. Any suggestioin is highly appreciated
