I implemented the CONNECT over SPDY support in Chrome.  Here are a couple
of docs we cooked up at the time

http://www.chromium.org/spdy/spdy-proxy-examples
http://www.chromium.org/developers/design-documents/secure-web-proxy
http://www.chromium.org/spdy/spdy-proxy

The first is the most concrete.  I could write up a I-D for this, if that's
the right way forward.  However, it seems like the behavior of CONNECT on
an HTTP/2 stream is pretty much identical to the behavior of CONNECT on an
HTTP/1 connection.

Cheers,

Ryan
