Answer 1

You need to append the jsessionid to all the URL's involved in your webapplication which are supposed to be invoked by the client. This includes the redirect URL's and the links in the JSP page.

In case of a redirect URL, you need to use HttpServletResponse#encodeRedirectURL() first:

response.sendRedirect(response.encodeRedirectURL("page.jsp"));

In case of links in a JSP page, you basically need to pass those URL's through HttpServletResponse#encodeURL() first. You can do this with help of JSTL's (just drop jstl-1.2.jar in /WEB-INF) tag, it will behind the scenes pass the URL through the aforementioned method:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
...
    ">link1
    ">link2
    ...
    
" method="post">
        ...
