title: Post data to JsonP
body: <p>Is it possible to post data to JsonP? Or does all data have to be passed in the querystring as a GET request?</p>
  
  <p>I have alot of data that I need to send to the service, cross domain, and it is too large to send via the querystring</p>
  
  <p>What are the options for getting around this?</p>
