what are the five technique for session tracking ? can you explain

[Achalveer Singh]

technique for session trackings--
1. URL rewritting
2. by using cookie
3. by session object
4.by hidden variables
fifth one i forget..............

[Achalveer Singh]

i think there are only four technique that i have posted for session tracking.

[Karthikeyan Varadarajan]

I think we are achieving the third one(Session Object) by using other three (URL rewriting, hidden variable and cookies ).

Session object will hold all the values related to user session and we may have some id kind of things (JSessionId).

The client will send the ID thro Cookies or URL Rewriting or Hidden variables. Thro� that ID , the server will fetch the session Object.


The simplified version is ,

If a session is required , Container will create a Session object and assign a ID to it. The send the ID to the client thro� Cookies or URL Rewriting or Hidden variable (I think now a days we are not using the third one).

From the next request onwards from the same client you will get the ID. Using that ID, that server will fetch the corresponding session object and do whatever it need.

So there are only three ways .

The session relies on one of the above methods for maintaining its state.
I know of three ways that containers maintain session state.

Session Cookies

URL-Rewriting

SSL Sessions

You, the application developer, could also use other methods, such as hidden form fields or cookies.
