Hi there Craig! So, do you have any advice about how could I make this?
What I am trying to do is to validate the user, which can only display the
HTML after being authorized by creating the session, understand?
He passes by a Login page, and if his password is ok, the session is
created by the getSession(true) method.
If the user try to view the page by directly typing the URL in the
browser, that servlet tests whether the session has been created or not,
and if it's not, it should redirect to an Error page or something like
that, got my problem?
The bad thing is that i want to finish this work quickly, i really can't
loose much time remaking everything...
Thanks...
