Multiple User Cookies

[MEM]

Hello,

Is there a way to make cookies unique for each user logging into an
asp application without overwriting the original cookie?

For example:

User A logs in as User A. A cookie is created on that users computer
with name, user_id, etc. Then User A logs in as User B - while still
logged into User A.

How do I prevent the original cookie from being overwritten? Or should
that first cookie be overwritten?

Need some help and advice...

Thanks in advance.
