[SQU] HTTP/1.0, persistent connections and HTTP/1.1

Hi

I was just wondering about one thing.

Let´s suppose that squid receives a HTTP/1.1 request from a web-client with a keep-alive connection in the header. Squid then passes it on and receives a reply (HTTP/1.1 or 1.0) with the connection: close header.
My question is : Does squid maintain a persistent connection between the client and the proxy even if the requested web-site(server) closes it after the reply ?

I also understand that Squid is not HTTP/1.1 compliant according to the RFC 2616 document.
How does squid react when it receives a HTTP/1.1 request/reply ? Does it downgrade the message version or just "tunnel" the message ?

Regards
