title: bower behind a proxy
body: <p><code>bower install</code> behind a proxy fails in timeout with the following settings (some set are useless...) :</p>
  
  <pre><code>git config --global http.proxy fr-proxy.example.com:3128
  git config --global https.proxy fr-proxy.example.com:3128
  
  export http_proxy=http://fr-proxy.example.com:3128
  export https_proxy=http://fr-proxy.example.com:3128
  
  npm config set proxy http://fr-proxy.example.com:3128
  npm config set https-proxy http://fr-proxy.example.com:3128
  
  npm config set registry http://registry.npmjs.org/
  </code></pre>
  
  <p>I have also tried an install/uninstall of bower and a <code>bower clean cache</code>.</p>
