How can I read data from the Forms Authentication Cookie

Hello,

I am using Forms Authentication to secure a site. I am using the "user defined data area" to store an account number. I am then encrypting the ticket.

eg/

string hash = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName, hash);



How can I read the "user data" in the cookie? Thanks for the help! ...
