The lifetime of persistent sessions. If zero, transient sessions are always used.
Assembly: System.IdentityModel.Services (in System.IdentityModel.Services.dll)
Tickets for persistent sessions are stored in file-based cookies, meaning that the sign-in session may continue after the web browser is closed and reopened.
This property is used to set the HttpCookie.Expires property.
The property can be initialized by specifying the persistentSessionLifetime attribute on the <cookieHandler> element in configuration.
