FrontController and Servlet Filters

Hi friends,

The problem which I am facing is slightly complex.

I have jsp page having many hyperlinks which request to a common Servlet (Front Controller). When the user clicks on a hyperlink the request forwards through another Servlet(Intercepting Filter). This Servlet checks whether the user has authenticated. If the user is not authenticated it shows a login page else the page which the user requested.

But the problem here is, once after the user authenticated from login page, he has to see the page which he had requested.

So what is the possible solution for this???

Please help me in this..

Thanks in advance,

Ratheesh narayanan

If I could understand this correctly:


why not try:

1. Extract the requested URL from the request object (e.g. req.getRequestURL).

2. if already logged in then forward to to requested URL.

4. If not logged in then store the requested URL in the seesion, a hidden field,as query string or as a cookie and forward the user to the Login page.

5. If a session, hidden field or query string value exist for the requested URL, then forward (if no bookmark required)/sendRedirect (if bookmarking required) to the requested URL value stored in your session/hidden field. otherwise forward to your home page.
