That's not actually true. I've never done what Maddy is suggesting myself, so, sorry Maddy, I can't directly answer your question except by suggesting you search the forum history because it has been covered before. I do know, though, that you can change the async methods to return something meaningful and doing so will give the caller control over the underlying XMLHttpRequest that will be used to make the RPC. It gives you the opportunity to modify request headers, inspect response headers, cancel inflight requests, modify timeouts, etc. The rest of your message was spot on, though--the return value for the RPC itself _is_ passed as an argument to the AsyncCallback's onSuccess method. What Maddy's looking for is a handle on the RPC action itself, as opposed to the value returned by the RPC.
