The resulting data should not be preceded by a bunch of jquery plus a bunch of callback functions why don't I have this?

Support error after console appears to be

JSONP requires server-side support, and if the server side supports cross-domain direct JSON on the line. If you do not support cross-domain you want to be able to modify the server-side support JSONP, but you can modify the support Jsonp why not modify the direct support across domains. If you can't change it, there's no way.

Jsonp works like this: When you request it, it passes to the server a function name, which is the random string in your debug that says no called, and then the server returns the code that calls the function, returning the data as a parameter to the call.

And you look at the Debug window, the returned data is a pure JSON string, so it is not jsonp.
