proxy

Borrowing from answers in this Stack Overflow question, here's how you can get through a corporate (Microsoft) NTLM Proxy to clone git repositories from drupal.org:

cd into your drupal contrib directory (or wherever you want to put the repository).

$ export http_proxy="http://username:password@proxy:port/"

$ git clone http://git.drupal.org/project/[projectname]

Recently, I was troubleshooting performance issues on a few different websites, and was stymied by the fact that YSlow repeatedly reported an F for "Compress components with gzip," even though online sites like GIDNetwork's Gzip test were reporting successful Gzipping of text components on the site.

Yslow results - not very happy.
