title: Ember Data sending OPTIONS requests after save
body: <p>After sucessfully updating an ember-data model, ember-data sends an OPTIONS request.</p>
  
  <p>First of all, I would like to know why it sends an OPTIONS request.</p>
  
  <p>And the actual problem is, that this options request is sent to the "location" where the put request returned from. Which is problematic because, I am using grunt-proxy and forward my requests to another domain. But the response from my PUT of course has this "other" domain as location. And the OPTIONS request ist then sent directly to this domain, which is of course not working due to CORS requests.</p>
  
  <p>Additional Comment:
  I found out that my PUT request returns a 302 Temporarily moved. I have to be honest, I have no idea, why because when I request my put Endpoint directly with some data, I never get a 302, always 204. 
  Could this be the reason why ember-data making the OPTIONS request?</p>
