and it really make things easier once I understand it.
I have 2 more questions:
I created my own Membership provider and profile provider (inherits from the ProfileProvider and MembershipProvider) so they do what I need and it work great on my developing computer.
1. Do I need to do something special when I make a release version?
2. About profile - I did not understand from the book if for each call for profile:
(in the way you described in the book - not my implementation of course) is actually asking the DB for the information or does it get the info from the memory or a cookie?
Just wanted to know the cost of using it.
