Parameters

context

An object that provides references to intrinsic server objects that are used to service HTTP requests.

callback

The method to call when the asynchronous method call is complete. If callback is null, the delegate is not called.

state

Any state data that is needed to process the request.

Returns

An IAsyncResult that contains information about the status of the process.

Remarks

When creating an HTTP handler for asynchronous use, your handler must implement the asynchronous DefaultHttpHandler.BeginProcessRequest(HttpContext, AsyncCallback, object) and DefaultHttpHandler.EndProcessRequest(IAsyncResult) methods that are called asynchronously by ASP.NET.
