title: Does AJAX have any special security concerns?
body: <p>I know all about SQL injections, and peeking into javascript files that a website uses, and also that GET requests contain all of the information in a URL.</p>
  
  <p>Is there any security concern that is special to AJAX and only pertains to using AJAX?</p>
  
  <p>For example, sending post requests via AJAX seems completely safe to me. Barring SQL injections, I can't think of one thing that could go wrong... is this the correct case?</p>
  
  <p>Also, are "requests" of any kind that a user's browser sends or any information it receives available to be viewed by a third party who should not be viewing? And can that happen to AJAX post requests ('post' requests specifically; not 'get')?</p>
