Connection pooling & Windows Integrated Security

I want to avoid asking for a user name and password on my intranet
applications so I decided to use windows integrated security. However
I wonder if connection pooling will work in this scenario or since
each user is connecting with a different windows credential the
connection won’t be in a pool. I was reading something about using
impersonation in asp.net but I don’t understand how it works and how
it will help with connection pooling.
