25 * The SessionValidator attempts to retrive the User object from the
26 * Servlet API session that is associated with the request. If the
27 * data cannot be retrieved, it is handled here. If the user has not
28 * been marked as being logged into the system, the user is rejected
29 * and the screen is set to the screen.homepage value in
30 * TurbineResources.properties.
31 *
32 * <p>
33 *
34 * Other systems generally have a database table which stores this
35 * information, but we take advantage of the Servlet API here to save
36 * a hit to the database for each and every connection that a user
37 * makes.
38 *
39 * <p>
40 *
41 * This action is special in that it should only be executed by the
42 * Turbine servlet.
