Hi all, I have a squid cache behind a stateful network device which drops idle TCP connections after 300 seconds. I need to ensure TCP level keepalives are set both for traffic to squid (accept) as well as traffic from squid (connect) in order to support long-lived connections with idle periods. I've found the "http_port keepalive" option, which does set SO_KEEPALIVE on the accept end of squid. But this directive doesn't set keepalives for outbound traffic, which I need as well. Would squid folks be receptive to a patch that adds a toplevel config directive to set SO_KEEPALIVE on all connections, both inbound and outbound? Or have I overlooked something and is this possible today? I'm relatively unfamiliar with Squid and am just starting to paw through the source to see what achieving this would take. Thanks!
