A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The system further includes a virtual path manager and a resource manager. The virtual path manager is coupled to the dispatchers through an inter-machine communication mechanism. The virtual path manager indicates to the dispatchers which of a cartridges is associated with the browser requests. The resource manager is coupled to the dispatchers through the inter-machine communication mechanism. The resource manager is configured to assign to each dispatcher of the dispatchers an instance of a cartridge of the cartridges in response to receiving a request for an instance from the dispatcher. The dispatchers are configured to send messages through the inter-machine communication mechanism to the instances that are assigned by the resource manager to the dispatchers. The messages cause the instances to perform the operations associated with the browser requests.

Method and apparatus for handling client request with a distributed web application server

A system, method, and computer readable-medium for performing operations associated with browser requests are provided. The system includes a plurality of dispatchers coupled to a plurality of web listeners. Each of the dispatchers receives from a corresponding web listener browser requests received by the corresponding web listener. The dispatchers are configured to send messages through an inter-machine communication mechanism to cartridge instances. The messages cause the cartridge instances to perform the operations associated with the browser requests. Each cartridge instances includes a cartridge execution engine and a cartridge. The cartridge execution engine handles all inter-machine communication with the dispatchers, and passes the requests to the cartridges by making calls into the application programming interface of the cartridge. Consequently, cartridges are isolated from the complexities of inter-machine communication, and may therefore by used in a highly distributed system without being distribution-aware.
