| 39 | * SessionValidator for use with the Template Service, the | |
| 40 | * TemplateSessionValidator is virtually identical to the | |
| 41 | * TemplateSecureValidator except that it does not transfer to the | |
| 42 | * login page when it detects a null user (or a user not logged in). | |
| 43 | * | |
| 44 | * <p>The Template Service requires a different Session Validator | |
| 45 | * because of the way it handles screens. | |
| 46 | * | |
| 47 | * <p>Note that you will need to set the template.login property to the | |
| 48 | * login template. | |
