| /** |
| * SessionManager implementation providing {@link Session} implementations that are merely wrappers for the |
| * Servlet container's {@link HttpSession}. |
| * <p/> |
| * Despite its name, this implementation <em>does not</em> itself manage Sessions since the Servlet container |
| * provides the actual management support. This class mainly exists to 'impersonate' a regular Shiro |
| * {@code SessionManager} so it can be pluggable into a normal Shiro configuration in a pure web application. |
| * <p/> |
| * Note that because this implementation relies on the {@link HttpSession HttpSession}, it is only functional in a |
| * servlet container - it is not capable of supporting Sessions for any clients other than those using the HTTP |
| * protocol. |
| * <p/> |
| * Therefore, if you need {@code Session} support for heterogeneous clients (e.g. web browsers, |
| * RMI clients, etc.), use the {@link DefaultWebSessionManager DefaultWebSessionManager} |
| * instead. The {@code DefaultWebSessionManager} supports both traditional web-based access as well as non web-based |
| * clients. |
| * |
| * @since 0.9 |
| * @see DefaultWebSessionManager |
