Gets or sets the authentication sliding expiration.
<ConfigurationPropertyAttribute("slidingExpiration", DefaultValue := True)> _ Public Property SlidingExpiration As Boolean
Dim instance As FormsAuthenticationConfiguration Dim value As Boolean value = instance.SlidingExpiration instance.SlidingExpiration = value
[ConfigurationPropertyAttribute("slidingExpiration", DefaultValue = true)] public bool SlidingExpiration { get; set; }
[ConfigurationPropertyAttribute(L"slidingExpiration", DefaultValue = true)] public: property bool SlidingExpiration { bool get (); void set (bool value); }
public function get SlidingExpiration () : boolean public function set SlidingExpiration (value : boolean)
When the SlidingExpiration is set to true, the time interval during which the authentication cookie is valid is reset to the expiration Timeout property value. This happens if the user browses after half of the timeout has expired. For example, if you set an expiration of 20 minutes by using sliding expiration, a user can visit the site at 2:00 PM and receive a cookie that is set to expire at 2:20 PM. The expiration is only updated if the user visits the site after 2:10 PM. If the user visits the site at 2:09 PM, the cookie is not updated because half of the expiration time has not passed. If the user then waits 12 minutes, visiting the site at 2:21 PM, the cookie will be expired.
The following code example shows how to access the SlidingExpiration property. Refer to the code example in the FormsAuthenticationConfiguration class topic to learn how to get the section.
' Get the current SlidingExpiration. Dim currentSlidingExpiration As Boolean = _ formsAuthentication.SlidingExpiration ' Set the SlidingExpiration. formsAuthentication.SlidingExpiration = False
// Get the current SlidingExpiration. bool currentSlidingExpiration = formsAuthentication.SlidingExpiration; // Set the SlidingExpiration. formsAuthentication.SlidingExpiration = false;
