More specifically, make sure it returns javascript (not just the data), and uses on of those content types...
There is a pattern that should cover your needs, call JSONP (JSON with padding), Google "jsonp" for more info. Basically, you have your server endpoint setup to return json data (as normal), but then add a check for a querystring parameter called something like "jsonp". The value of that parameter then becomes the name of a function call that the server wraps the json data in. So, a normal request to http://localhost/somePage returns json: {"foo": "bar"} But adding the jspnp parameter to the request ( http://localhost/somePage?jsonp=someFunction) returns javascript+json... someFunction({"foo": "bar"}); Note that this requires the "someFunction" function to be at the global scope level. There are many ways to skin this cat, really. JSONP is one of the simpler examples.
