Mock question -- security

The following web page is defined as the custom form login page for authentication. Assuming that you have attempted to access a protected resource and been redirected to this web page, what is the result of filling in the user name and password fields and pressing SUBMIT? (Choose one.)
<html>
<head><title>Login Form</title></head>
<body>
<form action="jsecuritycheck" method="POST>
<br />Name: <input type="text" name="jusername" />
<br />Password: <input type="password" name="jpassword" />
<br /><input type="submit" value="Log In" />
</form>
</body>
</html>
A.You will not be redirected to this page in the first place.
B.HTTP 401 or 403 error (forbidden/not authorized).
C.HTTP 404 error (page not found).
D.HTTP 500 error (server error).
E.The page is redisplayed.

answer is E.

I think it should be C, and I tried it, it's HTTP 404 error (page not found). I am using TomCat 5.5.

I would have guessed C as well, since an action of "jsecuritycheck" has no special meaning. In order to invoke the authentication check it should be "j_security_check".

Thanks Ulf.
