Really interesting, but where / how is the user's session data stored? client side or server side? From the article: There are two ways to do this. Firstly, each time a web page is requested, embed the entire context of the session into it so that the context is returned whenever a request is generated from that page. Alternatively, the application server has to maintain a list of all the contexts of all active sessions and associate each context with a session identifier. [...] I chose to implement a web session library based on the second concept. That would make it server side.
