Abstract: Many computer networks including the Internet and World Wide Web applications, use “stateless” protocols in that each request for information is independent of any other requests. However, many applications require state to be managed in some way, for example, a server remembering that a client submitted an acceptable password earlier in a session. The present means of managing state such as using cookies or complex URLs with embedded state, add load to the system resources. The invention lies in maintaining (26) the state on the client side, between a local browser and micro server, and only uploading (28) processed data to the remote server when required.
