Subject: [PATCH] proxy support: update HTTP CONNECT to conform RFC2616
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When connecting to the proxy we should include the Host-header into the
request. This is required by RFC2616 section 14.23 "A client MUST
include a Host header field in all HTTP/1.1 request messages".

While without this change some proxies reject connections, no such
problems appear with this patch applied.
