You got me wrong then. Squid 2.x will only issue HTTP/1.0 style
persistent outbound requests (Connection: Keep-Alive).

Connection persistanse is maintained separately between
browsers<->proxy_servers and proxy<->upstream (parent/origin).

* If a HTTP/1.1 client or a HTTP/1.0 client capable of persistent
connections connect to Squid then the client connection will be kept
* If Squid connects to a server capable of HTTP/1.0 style persistent
connections then the server connection will be kept open.
