FormsAuthentication.Timeout Property

Gets the time-out value, in minutes, that is specified in the configuration file.

Namespace:  System.Web.Security
Assembly:  System.Web (in System.Web.dll)

public static TimeSpan Timeout { get; }

Property Value

Type: System.TimeSpan
The time-out value in minutes that is specified in the configuration file. The default is 30 minutes.

This property gets the time, in minutes, after which the cookie (ticket) expires. If the SlidingExpiration property is true, the Timeout property is a sliding value, and it expires at the specified number of minutes after the time that the last request was received. To prevent compromised performance, and to avoid multiple browser warnings for users who have cookie warnings turned on, the cookie is updated when more than half of the specified time has elapsed. This can cause a loss of precision.
