This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
Is it possible for a POSTed form's data to remain intact across a form-login authentication scheme? The servlet spec says for login-form authentication, it will "save the URL path" that triggers the authentication, and use it after the user successfully is authenticated.
I'm guessing that ambiguity will lead to server mismatches--some being able to reconstruct the full request after authentication, while others only reconstruct the request but miss the message body.
On a related note, after the user gets authenticated, is there any difference between the original request and the one that you see after authentication? Will, for example, the referring URLs be identical, or will the final one be changed to reflect some bizarre authentication URL the container comes up with?
