Abstract: A software framework for implementing distributed applications is provided. An implementer's client-specific code functions through the framework's client-side software. The implementer's server-specific code contains system-specific business logic and functions within the framework's server-side software. Communication is provided by the framework between each instance of implementer's client-specific code through an instance of client-side software to implementer's server-specific code through the server side software over at least one communication link. Multi-threaded communication is achievable over a single communications link, even where the implementer writes single-threaded code. The client-side software is able to process synchronous and asynchronous messages received from the server-side software while simultaneously sending additional messages to the server-side software, which can be processed concurrently by said server-side software.
