There is not much to configure. Squid does not support the Upgrade header yet so WebSockets should be using CONNECT requests. CONNECT are governed by two timeouts: http://www.squid-cache.org/Doc/config/read_timeout/ http://www.squid-cache.org/Doc/config/client_lifetime/ and the destination server port number is usually restricted to the ACL set called SSL_ports, which usually only contains port 443.
