That's the difference between a redirect and a forward: a redirect instructs the client to request a different URL from the server, which thereby creates a new request object; a forward is handled entirely on the server, with the server simply redirecting the *handling* of the request to something other than what was initially requested.

Well, I tried switching to 2.4 spec, but the only difference (I enabled requests and
forwards), is that it now prints the url twice (i.e. the doFilter method is called twice),
but it still just shows me the url for the previous page ( i.e. /logins.jsp instead of
/protected/index.jsp but the page shown is /protected/index.jsp)
Is there something fundamental I am missing...? This is my first JSF app, but it shouldn't
be that much different from say Struts...
