Method and system for dynamically loading server code on a client to support multiple veresions of client and servers in a client/server application

摘要

A client host obtains software by establishing a session with a server host, and downloading software from the first server host for use during the session to implement a client side of a particular version of a network application. The software is compatible with software executed at the server host to implement a server side of the network application. Moreover, the client host may establish sessions at the same time with other server hosts by downloading software from the other server hosts for running a different version of the same application, or a different application. The client host may also establish multiple sessions with the same server host to run different applications. In an analogous procedure, a server hosts downloads software from one or more client hosts.
