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.
