[FIXED] In how many ways we can track the sessions in servlet?

Issue

What are the different ways to track the session in servlet. Is it is possible by using hidden files ?

Solution

There are three ways

• hidden form fields
• cookies
• url encoding.

One of the ways is to use HttpSession You can create session using

HttpSession session = request.getSession();

or you can use HttpSession session = request.getSession(true). Both statements mean that If there is associated session with this user, then return that one or create a new session. If false is passed, then new session is not created.
