You can also rewrite the URL. For instance:
/foo.jsp
Is your page. Instead of putting a form in it you can write it as:
/foo.jsp?page=1
And achieve the safe effect as a hidden form parameter. You could also
deploy the servlet to multiple URLs, for instance:
/foo.jsp
/foo2.jsp
/foo3.jsp
Then use HttpServletRequest getRequestURI() to figure out which page is
being requested.
