There are certainly better ways to solve the <em>actual</em> functional requirement than this ;) As I commented in your <a href="https://stackoverflow.com/questions/3092917/how-can-i-get-the-tomcat-jsessionid-on-the-client-side">follow-up question</a>:</p> <blockquote> <p>This is the 2nd time that you asked a question which in real world should never be practiced. Honestly said, this all smells. What is it, the problem for which you think that getting the <code>HttpSession</code> associated with JSESSONID in server side and getting the JSESSIONID value in client side is "the" solution? Elaborate about this in a new question, you'll get answers how to do it the right way. </p> </blockquote> <p>Take it serious. We're not teasing you, we're just trying to help you in the right direction to avoid that your project/webapp will break due to security holes and bad practices and/or that you will get fired.</p>
