One problem... how does the Container know who the client is?

The HTTP protocol uses stateless connections. The client browser makes a connection to the server, sends the request, gets the response, and closes the connection. In other words, the connection exists for only a single request/response.

Because the connections don’t persist, the Container doesn’t recognize that the client making a second request is the same client from a previous request. As far as the Container’s concerned, each request is from a new client.
