You are not really asking the same question here.
"request.getRequestedSessionId()" asks the servlet container "what session ID
was requested in this request?" The first time in, there won't be one, because
the browser does not know it needs to be in a session until you tell it (by
sending the cookie, or doing the appropriate URL rewriting).
To find out the session id of the session you just created, call
session.getId() instead.
