Is it possible to create a generic handler that implements the ICallbackEventHandler interface? I have a generic handler that returns a sting of JSON data but I cannot figure out how to use that data in JavaScript without a callback function. Google and Yahoo! have web services that return JSON data and support callback functions so I know how to use their data in JavaScript. 

 Is there a reason you want to use an ICallbackEventHandler when you can do it pretty easily without it.

 Here is an example of calling the Yahoo Traffic API

I am not using the Yahoo! API. I am trying to create my own web service proxy which will convert any RSS feed into JSON. I have the web service working as a generic handler. The only problem is that I cannot figure out how the client JavaScript can use that JSON data without a callback function. I've seen how to use JSON data from Google and Yahoo! in client JavaScript using a callback function. I cannot find any sample code for creating a callback function in a generic handler. Right now I'm trying to use Jayrock.
