I'm trying to make a condition in my index page, that condition must verify if the password that the user insert in the form is the correct  password or if it is incorrect, i need to show a message in the same page that says sometime like "incorrect password" something like that, but when i try to do this i just get the following page:

But i don't want this redirection, in fact the message of incorrect password need to be shown in the same index page, is it possible to do this kind of verification in Lotus Domino?? because it seens to be authenticating  internally, so i need help to make that authentication happen in the same page or at least the name of the form i need to modify for this authentication.
