silverlight authentication

Good day!

I have an silverlight site (silverlight navigation application) and I want clients to log in on my site. I want to give them different rights of viewing pages. A WCF service gives me true or false when I enter a login and a password. Then, i开发者_如何学编程f it returns true, I want to remember the logged user.

How can I do it? Using cookies or global variable or something else?

You should look at WCF RIA Service in a combination with the ASP.NET Membership Provider. There is also a Template for an AuthenticationService... Examples here:

Although www.codeproject.com/KB/silverlight/SL3WindowsIdentityName.aspx is based upon Windows Authentication, could you not adapt the first part of it for your needs?
