ENHANCEMENT: Applying the asynch request patch to our tag field. We use a simple queue management idea to keep only the latest ajax request is valid, ie, we abort all requests before the current request is submitted, so that there is only at most one request spanning in the client side, so no early request's response cover late request's response, also greatly enhance the performance of both sides, especially in case of complicated operations in server side and complicated post-events in client side.
