34 | /** | |
35 | * SessionValidator that requires login for use with Template Services | |
36 | * like Velocity or WebMacro. | |
37 | * | |
38 | * <br> | |
39 | * | |
40 | * Templating services requires a different Session Validator | |
41 | * because of the way it handles screens. If you use the WebMacro or | |
42 | * Velocity Service with the {@link DefaultSessionValidator}, users will be able to | |
43 | * bypass login by directly addressing the template using | |
44 | * template/index.wm. This is because the Page class looks for the | |
45 | * keyword "template" in the Path information and if it finds it will | |
46 | * reset the screen using it's lookup mechanism and thereby bypass | |
47 | * Login. | |
48 | * | |
49 | * Note that you will need to set the template.login property to the | |
50 | * login template. | |
