title: XHR request hangs in safari on el capitan
body: <p>I have a wierd situation that we cannot figure out or make sense of.</p>
  
  <p>We have a web application.  If i use chrome on osx it works.  If i use safari and hit our QA environment it works.  If i run safari on Mavericks against my local dev machine it works.  If i run safari on el capitan against my local dev machine to does NOT work.</p>
  
  <p>What we see is that the browser is able to directly download assets but xhr requests sit there and spin indefinitely.  One of the examples is were using angular with routing and when angular makes the xhr for the html page it sits there and hangs.  However if i just put the same url into the browser itself it pulls down the html just fine.</p>
  
  <p>This has stumped us.  It worked fine in Mavericks, it works fine in our QA environment.  We have turned off all firewalls on the local dev machines.  The iis logs on the local dev never see the request for the html file.  Chrome on el capitan works just fine.</p>
  
  <p>Does anyone have any ideas?</p>
