JSONP

•  JSONP is only for GET, though, not POST 
• http://stackoverflow.com/questions/6809053/simple-jquery-php-and-jsonp-example
• Basically, Server Side: need to return something like "CallbackFunctionName({'data': 'value'})"
• Client Side: type is JSONP, add ?callback=CallbackFunctionName to the GET request
  

 There is another way to make cross domain call
