| /** |
| * Filter that allows access to a path immeidately without performing security checks of any kind. |
| * <p/> |
| * This filter is useful primarily in exclusionary policies, where you have defined a url pattern |
| * to require a certain security level, but maybe only subset of urls in that pattern should allow any access. |
| * <p/> |
| * For example, if you had a user-only section of a website, you might want to require that access to |
| * any url in that section must be from an authenticated user. |
| * <p/> |
| * Here is how that would look in the IniShiroFilter configuration: |
| * <p/> |
| * <code>[urls]<br/> |
| * /user/** = authc</code> |
| * <p/> |
| * But if you wanted <code>/user/signup/**</code> to be available to anyone, you have to exclude that path since |
| * it is a subset of the first. This is where the AnonymousFilter ('anon') is useful: |
| * <p/> |
| * <code>[urls]<br/> |
| * /user/signup/** = anon<br/> |
| * /user/** = authc</code>> |
| * <p/> |
| * Since the url pattern definitions follow a 'first match wins' paradigm, the <code>anon</code> filter will |
| * match the <code>/user/signup/**</code> paths and the <code>/user/**</code> path chain will not be evaluated. |
