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"));
