| /** |
| * The SessionValidator attempts to retrieve the User object from the |
| * Servlet API session that is associated with the request. If the |
| * data cannot be retrieved, it is handled here. If the user has not |
| * been marked as being logged into the system, the user is rejected |
| * and the screen is set to the screen.homepage value in |
| * TurbineResources.properties. |
| * |
| * <p> |
| * Other systems generally have a database table which stores this |
| * information, but we take advantage of the Servlet API here to save |
| * a hit to the database for each and every connection that a user |
| * makes. |
| * </p> |
| * |
| * <p> |
| * This action is special in that it should only be executed by the |
| * Turbine servlet. |
