Simple Redirect Plugin

I am in the process of creating an integrated login for word press, and I have most the problems solved, except redirecting users to different login/logout and profile edit pages. I was hoping that the auth_redirect would be called anytime that an unauthorized user tries to access a page that requires authentication, but that does not seem to happen. Also, I wanted to redirect a user for a logout request as well as a profile update. I did add a simple action hook for set_current_user the looks at the $_Server[“REQUEST_URL”] variable, and conditionally redirects the user, however, this has the dis-advantage of showing original WP page, before redirecting.

Anyway, I was hopeful there might be a way to do this with a plug-in, but I am not sure.
