[Ramakrishna Udupa]

Hi All,

I don't know where to ask this J2ee Question. Sorry, because If I'm asking this question in wrong Place.

What is the difference between JSESSION ID and Session?
I red THIS blog, I got the explanation but I'm actually confused about JSESSION ID and Session..
In that blog, they told about JSESSION ID cookie. then

What is the difference between JSESSION ID and Cookie?

Please give me proper explanation.

Thanks:

Hmm let see if I can explain this:

A (HTTP) session is an object that can hold conversational state across multiple requests for the same client. You can put "attributes" into this session. Each session has a unique "session ID" to determine who the client is.

Now how does the web container know what the session ID is? Through cookies.

A cookie is then an object that contains this unique session ID (apparently called JSESSIONID) and other stuff. This cookie is passed to the web container for it to identify who the client is.


Hope my explanation helps.

I'm sure Bear would have a better explanation.
