Hi, Frits, thanks for your reply.
I have a question. If the response has been committed, why the HttpSession object cannot be used for subsequent requests?
HttpSession object is used for a sequence of requests.
According to Charles 's book, a client sends the first request within a session.
The
servlet responds with a jsessionid. (This response is committed to the client ?)
The client sends a second request within the same session with the jsessionid.
The servlet responds to this request with that jsessionid. (This response is also committed to the client?)
