title: What does "DIRECT" in a PAC file signifies
body: <p>I have a PAC file that I need to parse to apply a proxy to the network. </p>
  
  <p>The content of the pac file is: </p>
  
  <pre><code>function FindProxyForURL(url,host) { 
          return "DIRECT";
  }
  </code></pre>
  
  <p>I want to know what <code>"DIRECT"</code> means here? How can I get the IP address of the proxy that's being used?</p>
