Re: The function for response.encodeURL....me still not sure

[Jon Wingfield]

You don't need to use encodeURL for includes or forwards. These are 
server side processes and the session has already been determined. The 
encodeURL tags the *next* client request with the data required to 
continue a session.

Thanks a lot,

But......for example...if I have a jsp file..that includes another jsp
file in it.....how can I write it with encodeURL? Doesn't seem to work..
E.g.
<%@ include file="<%= response.encodeURL("header_status_register.jsp")
%>" %> doesn't work

As I said, the URL-rewriting is done by the container to allow you to
use HTTP sessions when the user of your site has disabled cookies and it
does this by appending ";jessionid=blah-blah-blah" to end of your URLs
prior to the query string ("?blah=stuff&jabber=yakka-yakka...").  This
is all in the servlet spec.  However, you need to give the container the
opportunity to do so and for this you need to use the encodeURL methods
of HttpServletResponse.
Think about your JSPs.  Currently (presumably) you have links like the
following:
    <a href="some_link.jsp">Some link</a>
To enable session tracking without cookies, all you need to do is:
    <a href="<%= response.encodeURL("some_link.jsp") %>">Some link</a>
Likewise, whenever the logic of your page indicates that a redirect is
required, instead of calling:
    response.sendRedirect("some_link.jsp");
you call
    response.sendRedirect(response.encodeRedirectURL("some_link.jsp"));
