title: How to trace strange Network calls in Google Chrome?
body: <p>In the developer tools, in a web app I'm working on, I'm getting a rather strange error in the console:</p>
  
  <p>'GET data:'</p>
  
  <p>That's it.  No stack trace or anything.  It is a failing network call.  It shows up in the Network tab:</p>
  
  <blockquote>
    <p>Request URL: data:</p>
    
    <p>Request Headers</p>
    
    <p>Referer: <a href="http://localhost/testapp/" rel="noreferrer">http://localhost/testapp/</a></p>

  </blockquote>
  
  <p>No error in Firefox/Firebug.  Would be nice to figure out what line of HTML/Javascript caused Chrome to attempt to execute this specific request.</p>
