Hi all,
I am writing a servlet which uses cookies to identify a user
on a web site. But I want the user to have an option of deleting
the cookie if a new user comes in. Somehow, I am not able to delete
the cookie for which I wrote the following code which is executed
every time the 'change user' link is clicked.
Please help me out as where am I going wrong or what might
be the possible mistakes.
Thanx in advance,
Yogesh Agarwal
