If I have a look at my cookievalue .ASPXANONYMOUS it is a string ie
WZnX-rXHygEkAAAAOTFhZjE5YTctZmEzZi00MTMwLWEwNTAtYjYwMzI0N2M0NTY4gQUsRlThiJWAjBgmBnpeIba7eGo1
The value Request.AnonymousID is a Guid.
How do you get from ASPXANONYMOUS to AnonymousID ?
I need this to debug some issues I have with FormsAuthentication.
Yes, an anonymous id is a GUID. The cookie string is an encrypted value containing the id and other data:
By default, anonymous cookies are valid for 90 days and are refreshed every visit.
You can treat Request.AnonymousID as the request username when Request.IsAuthenticated==false.
see AnonymousIdentificationModule
UPDATE: In response to a comment, yes, you can decode the value, but why?
