Access through a proxy
The Mercurial client can go through a proxy, if you configure it to do so. First, edit your "hgrc" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is called "~/.hgrc". On Windows it is in "%USERPROFILE%\mercurial.ini". There is a per-repository version called .hg/hgrc at the top level of each repository. Documentation is here.
