When a homepage, or login page is requested we must check if a User has logged in, and forward them to the right spot. The action will usually look for a mapping forward called " loggedout" in the struts-config.cml file, that represents the page to forward control to if the user is not logged in. This action will load an appropriate HomepageChooser to decide where to send a logged in user, depending on its class. Note the is homepages are special because they are the only pages of mixed public/private content that have a single url. also of special note is that this action executes any specified actor or presentation controllers whether logged in or out. if you want logic specific to a logged in user then load the session when you login that user using the UserLoginController. The rest should be split up into /in/, /out/, /admin/ etc subdomains where the AccessControlFilter can decided how to handle the request.

Parameters:

mapping - The ActionMapping

form - The Struts ActionForm

request - The servlet request.

response - The servlet response.

Returns:

an action forward.

Throws:

Exception - if something broke.
