Hi everyone I am unable to understand the session management concept
I am providing the program and I will tell exactly where I am stuck


as far as my understanding goes :-
when the client enters his name and age in the form.html the request
goes to scwcd servlet where we get a session object then the request
is dispatched to a second jsp asking him for plot no and when the user
enters the plot number the request goes to "testservlet" servlet where
I have written a line (req.getsession()) as my second request carries the
session id it is matched and the server comes to know that this another request from the same client and when I write get attribute it gives me back the set attributes and I display it uptill this it is ok but when I disable the cookies the server should generate a new session object and getAttributes should return null but in my case I am getting the set attributes. I am confused.either there is a flaw in my understanding
or somehow I am not disabling the cookies in my IE....,

Please help to let me know where I am wrong
Thanks in advance(for showing patience!!!)

Abhisek,
Cookies aren't the only way of keeping a session alive. URL Rewriting is another one (jsessionid shows up on the URL). So your session can be active without a cookie.

Also, session cookies are treated differently than persistent cookies. Check if your browser is disabling session cookies too. If not, turning off cookies isn't preventing a session.

I don't use IE so I haven't tried this. However I see something that looks relevant.

Internet Options --> Privacy Tab --> Advanced - to get the settings box
Check override automatic cookie handling to enable options
Select block first party cookies
As long as "always allow session cookies" is unchecked, I think IE would block them.

Hi Abhishek,

I did try this code on my system using IE8, I was able to replicate this problem but when I restarted the server, the code produced the desired result i.e it displayed null.

As far as I know, the enabling and disabling of cookies should not be dependent on the context. Any expert comments on this please?

Thanks.
