I use a single HTTPService instance, and a single result handler.
The send() method returns an AsyncToken, which is a dynamic object to which you add most any kind of property you want. The result handler function can access this AsyncToken and read those proerties. I typically set a "callId", which is a string that identifies the call, and sometimes a "nextaction" property when I invoke a dataservice call. In the result handler, I use a switch statement to conditionally work with those properties to determine the next appropriate processing step, which obviously can include another dataservice call. The switch statement can get pretty long, but is easy to understand, debug and modify. With a single breakpoint, I can monitor every result.
