CreatingCookieEventArgs::CookieIsSet Property
Gets or sets a value that indicates whether the authentication cookie has been created.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
The AuthenticationService class checks the CookieIsSet property to determine whether the authentication cookie has been created. You set this value to true if you create an authentication cookie in an event handler for the CreatingCookie event. If CookieIsSet is set to false (the default value), the AuthenticationService class creates an authentication cookie, This overwrites any cookie that you have created in the handler for the CreatingCookie event.
The following example shows an event handler for the CreatingCookie event. The handler retrieves user values from the CreatingCookieEventArgs object to customize the authentication cookie. The CookieIsSet property is set to true after the authentication ticket is created.
