If you read the precise semantics of isRequestedSessionValid(), you
will see that this behavior is exactly as it should be.
Consider the following timeline:
(A) Request 1 comes in:
- With no session id (because the session did not exist yet
- Calling request.getSession() creates a new session,
but one that the client doesn't know about yet
- request.isRequestedSessionValid() returns false
- You render the page, including the session id
(B) Request 2 comes in
- With a session id
- Therefore request.isRequestedSessionValid() will return true
