I'm not entirely sure I understand your problem, but I'll take a stab at it anyway.... Typically, you don't need to worry about where the sessionid comes from. Anywhere you send a redirect or put a link in a JSP or servlet generated html, you should ALWAYS use HttpServletResponse.encodeURL() or HttpServletResponse.encodeRedirectURL(). Once tomcat knows whether or not the browser is using cookies, it will encode the URL as needed. If cookies are enabled, the URL will be unchanged. If no cookies, the session ID will be inserted. Tomcat does this for you. You don't need to worry about it, just encode ALL URLs.
