title: Bower calls blocked by corporate proxy
body: <p>I'm trying to use Bower for a web app, but find myself hitting some sort of proxy issues:</p>
  
  <pre><code>D:\&gt;bower search jquery
  bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 1.2s
  bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 2.5s
  bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 6.8s
  bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 15.1s
  bower retry         Request to https://bower.herokuapp.com/packages/search/jquery failed with ECONNRESET, retrying in 20.3s
  bower ECONNRESET    Request to https://bower.herokuapp.com/packages/search/jquery failed: tunneling socket could not be established, cause=Parse Error
  </code></pre>
  
  <p>Relevant points:</p>
  
  <ul>
  <li>I can browse to <a href="https://bower.herokuapp.com/packages/search/jquery">https://bower.herokuapp.com/packages/search/jquery</a> and it returns a full json response.</li>
  <li>I can use git to clone, both using the git:// protocol and http(s).</li>
  <li>I can use NPM directly without these issues</li>
  <li>I've tried using Fiddler to determine what's being blocked, but it doesn't detect any calls from the Bower command.  I can see calls from NPM commands in Fiddler.</li>
  <li>I've searched the Bower issues list, seen similar issues, but they either have no solution or it doesn't seem quite the same as mine.</li>
  </ul>
  
  <p>Any ideas?</p>
