Original by fancyf (fancyray) http://blog.9cbs.net/fancyf/ After the "ASP.NET Forms Authentication" is finished, "I feel that it can be empty for Forms, and the result is initially issued. The owner mentioned a question: How is MachineKey implemented? Is the MachineKey used by different web applications on the same virtual host? I didn't expect this question last time, and I did a try. Test Idea: Newly built a WebApplication on the same computer, the domain name bound is not the same, nor is it in the same application pool.

THIS.TXTUSERNAME2.TEXT, GENDATE, GENDATE.ADDYEARS (50), true, "", "/") ;THIS.LBLENCRYPTEDCOOKIE.TEXT = Formsauthentication.encrypt (Ticket1); Running Discovery, the same username and generating time The results obtained by FormSauthentication.encrypt (Ticket1) are different each time, but each result is valid.
Now this page to get WebApplication newly created run, the result of a group placed on the original WebApplication Login.aspx page:
