How many types of Cookie are there ???

Well there are no server side cookies. Cookies are usually handed over to clients over HTTP so that clients can be stateful. Everytime, the browser says to the server, "Hi server do you remember me ? I am the guy with the JSessionID=blalba!123%^&D". If you dont want to use cookies use HTTPS or URL rewriting.
