Class UrlSessionFilter

public class UrlSessionFilter extends Object implements Filter

Sample filter to use url's instead of cookies for sessions. When html files are delivered, all URL's back to this host are changed to add in the session information. When requests are made, the session info is stripped off the URL, which is passed to the rest of the handlers.

Note: This fiter has been superceded by the SessionFilter. It is included for illustrative purposes only.
