  • setting an indicator to a first state in the client memory;

    detecting a request submission at the client to send a request to the server;

    testing said indicator, and if said indicator is set to said first state, then submitting the request to the server, and resetting the indicator to a second state, if said indicator is set to said second state, ignoring the request submission and raising an error condition;

    thereby reducing network traffic associated with duplicate request submissions.
