Sending the request for the data and receiving the data (together with invoking this event) proceed asynchronously, i.e. after sending the request the viewer operates further, it is controllable, ... After the server processes the request, it sends the result back to the viewer and the viewer processes it (the viewer doesn't wait for processing the data by the server, the data can come to the server even with a delay depending on the quality of the connection).
