Except that HTTP/1.1 doesn't define "Connection: keep-alive", only "Connection: close". The keep-alive of an HTTP/1.1 connection is implicit by the protocol being HTTP/1.1. "Connection: keep-alive" is keep-alive of a HTTP/1.0+ style persistent web server connection. HTTP/1.0+ defines different signaling for web servers and proxies due to Connection not being an HTTP/1.0 header making it likely proxies does not understand Connection: keep-alive.. A client accepting "Connection: keep-alive" as keep-alive of a proxied connection is broken not respecting the Netscape specifications for keep-alive for HTTP/1.0. Regards Henrik
