commit 41328c700992433fe3900fcbb78d62340ba197f2 Author: David Fifield david@bamsoftware.com Date: Sat Oct 6 20:40:18 2012 -0700

Decorate addresses given to a HTTP CONNECT proxy.

This affects the Request-URI and the value of the Host header. RFC 2616 doesn't directly address the formatting of IPv6 addresses, but it delegates some productions to RFC 2396 "Uniform Resource Identifiers (URI): Generic Syntax," which is obsoleted by RFC 3986, which requires square brackets for IPv6 addresses in both places.

I tested this with HTTPSProxy 127.0.0.1:8000 Bridge <IPv6 bridge> UseBridges 1 and an Ncat HTTP proxy: ncat --proxy-type http -l 8000 -vvv
