Question

I understand that if we use the following statement

HttpSession session = request.getSession();

Will create the Unique session id, Create Cookie and associate Cookie with the Session id.

and helps the container to keep track and identify the clients.

Yes, My question, is there a possibility for me to see the cookie header and Unique Id created by this statement request.getSession()?

Answer 1

You can retrieve a HTTP Header using
HttpServletRequest.getHeader.

Although a session can be created by calling HttpServletRequest.getSession(true)
it’s rather done by the webcontainer. As edl already wrote HttpServletRequest.getSession().getId() returns the session id.
