Most web applications need to keep track of the people using the application.
\nHTTP has some rudimentary support for maintaining a user logon, but the approach is limited and not secure.
\nThe Java servlet framework does provide support for a robust user session but needs a mechanism to maintain<\/p>\n
the session across HTTP.
\nThe jsessionid is a key maintained by the container to track the user session via HTTP.
\nIncluding the session key in a hyperlink is called URL rewriting. The Servlet Specification [Sun, JST] encourages
\nthe use of cookies to maintain the session. When that is not possible, URL rewriting is used
\ninstead. The first time a browser makes a request to the container, the container does not know
\nwhether the browser will accept a cookie. The container can offer the browser a cookie, but can\u2019 t
\ntell if it was accepted until the next time a request is made. (HTTP has no \u201c handshaking.\u201d ) In the
\nmeantime, the response for the current request must be written. So, the first page written for a
\nbrowser will always need to use URL rewriting. If on subsequent requests the container finds that
\nits cookie was accepted, it can skip rewriting the URLs.<\/p>\n
