Container Managed Authentication enhancements in Tomcat 5.0.4

When playing around with Tomcat 5.0.4 today, I noticed a couple improvements. I use container-managed security on all my apps, and there were a couple of things that annoyed me about 4.1.x:

  • When the user is routed to the form-login-page, the URL (i.e. "/login.jsp") appears in their browser's address bar. Therefore, when you try to do request.getRequestURL() (to find the URL they originally requested), you're SOL - you get "/login.jsp" instead.
  • I have a 400 (invalid reference to login page) error-page routing to index.jsp (which redirects to /do/mainMenu). This should allow a user to bookmark "/login.jsp" and, once authenticated, they will be routed to the mainMenu. In Tomcat 4.1.x, I get routed back to the login page, and the user has to login again to get to the mainMenu.

I'm happy to report that both of these bugs are fixed in Tomcat 5.0.4. When I'm routed to the login page, the browser's address bar says the URL I requested (/do/mainMenu), rather than "/login.jsp". Also, request.getRequestURL() does return the URL I originally requested, not the login page. This is awesome IMO b/c now users will not bookmark "/login.jsp". And even if they do type it in, my 400 error page routes them to "index.jsp" which goes to the main menu. All of this did not work in 4.1.24 and now it does in 5.0.4. I'm going to start using 5.0.4 for my dev environment. Oh yeah, Roller runs fine on it too. ;0)

Having 400 error page doesnt help me. This is what I did. Added <error-page> <error-code>400</error-code> <location>/400.jsp</location> </error-page> 400.jsp has just one line <% response.sendRedirect("index.jsp");%> Now when I try to access /login.jsp I get login page, when I try to login, I get forwarded to 400.jsp which inturn tries to forward to login.jsp again as index.jsp is protected, when I try to enter credentials again, I get the error : HTTP Status 404 - /index.jsp Am I doing anything wrong?
