| /** |
| * SessionManager implementation providing Session implementations that are merely wrappers for the |
| * Servlet container's 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 JSecurity |
| * <tt>SessionManager</tt> so it can be pluggable into a normal JSecurity configuration in a pure web application. |
| * |
| * <p>Note that because this implementation relies on the <tt>HttpSession</tt>, it is only functional in a servlet |
| * container. I.e. it is <em>NOT</em> capable of supporting Sessions any clients other than HttpRequest/HttpResponse |
| * based clients. |
| * |
| * <p>Therefore, if you need heterogenous Session support across multiple client mediums (e.g. web pages, |
| * Flash applets, Java Web Start applications, etc.), use the {@link DefaultWebSessionManager WebSessionManager} instead. The |
| * <tt>WebSessionManager</tt> supports both traditional web-based access as well as non web-based clients. |
