BTW, one issue that's been bugging me for awhile is the need to store
the proxy password into hgrc, since in my case it's actually the same
as the windows active-directory password. Somehow when I use the same
proxy server on the web browser (IE & Firefox), I am not required to
provide these info. I am no expert on this topic, it'd great if some
guru out there is able to create an Mercurial extension that can
handle proxy in the similar way, include bypassing the proxy server
automatically when I have direct connection to the internet while I am
not within the company network.
