title: cURL 5 - Proxy not resolved
body: <p>I am trying to execute the following:</p>
  <p><code>curl twitter.com</code></p>
  <p>But I have got the proxy <code>http://proxyurl:port</code> set in <code>~/.curlrc</code></p>
  <p>However, when executing <code>curl twitter.com</code> I am getting</p>
  <pre><code>curl: (5) Could not resolve proxy: proxyurl
  </code></pre>
  <p>I have tried almost everything such as defining http_proxy in <code>~/.bashrc</code></p>
  <p>But still no luck.</p>
  <p>So two questions, what does it mean by could not resolve proxy,</p>
  <p>and secondly how do I resolve it.</p>
  <p>Thanks in advance.</p>
