Abstract: A system and method for context management which addresses the above problems while isolating the context management functions from the other functional code found on the server system. The context management system includes a context manager component which stores and retrieves name-value pairs describing the context in which the current request is being processed. In doing so, three types of context data are distinguished: static, dynamic, and transient. The context manager stores context data regarding each of a user's sessions and page flows, and returns context data in response to requests from the server system. Using this context data, the server system can then interact with the user in a manner appropriate to the user's context.
