Session tracking.
HttpSession interface is utilised in this example.
First a check is performed whether the request includes a "cookie" header and 
a validity test based on the requested session id.
If the client user agent is checked not to support cookies, URL rewriting is used instead. 
In that the session id is encoded as a path parameter in the resulting URL string.

boolean cookiesCheck = request.getHeader("cookie") != null && request.isRequestedSessionIdValid();
final String jsessionID = cookiesCheck ? "" : ";jsessionid=" + session.getId();
