title: How to debug a failed ajax request in google chrome?
body: <p>I have a web application that crashes on ajax requests with google chrome (it works with every other web browser it was tested it). After debugging I found that the error is caused by response.responseText being undefined. The xhr object looks like this:</p>
  
  <pre><code>argument: undefined
  isAbort: false
  isTimeout: undefined
  status: 0
  statusText: "communication failure"
  tId: 3
  </code></pre>
  
  <p>In debugger in the 'network' tab I get "(failed)", however all the headers are there and I can even copy into clipboard the response body (which is a valid JSON).</p>
  
  <p>My question is - how can I debug this problem? Where to find additional information, what causes this request to fail?</p>
