title: UrlFetchApp unable to access localhost resource
body: <p>This works fine:</p>
  
  <pre><code>var resp = UrlFetchApp.fetch("someremotehost/SomeFile.csv");
  resp.getResponseCode();  //returns 200
  resp.getContentText();   //returns the data
  </code></pre>
  
  <p>however, on my local machine, I'm running xampp with SomeFile.csv is located in htdocs/dev but I cannot get it to work on localhost:</p>
  
  <pre><code>var resp = UrlFetchApp.fetch("localhost/dev/SomeFile.csv");
  resp.getResponseCode(); //returns 0.0
  resp.getContentText()   //returns nothing!
  </code></pre>
  
  <p>I checked with chrome-extension postman and <code>http://localhost/dev/SomeFile.csv</code> works fine, so why does <code>UrlFetchApp.fetch("http://localhost/dev/SomeFile.csv")</code> not work?</p>
