CacheSection.DisableExpiration Property

Gets or sets a value indicating whether the cache expiration is disabled.

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

[ConfigurationPropertyAttribute("disableExpiration", DefaultValue = false)]
public bool DisableExpiration { get; set; }

Property Value

Type: System.Boolean
true if the cache expiration is disabled; otherwise, false. The default is false.

If the DisableExpiration property is set to true, the cached items never expire. This setting is intended to help debug cache behavior in application code. Use caution when disabling cache expiration, as this might result in items being cached longer than they are valid.

NoteNote:

To add a page to the output cache, you must establish an expiration policy for that page. You can do this declaratively with the @ OutputCache directive or programmatically using the SetExpires method. For more information, see How to: Set Expiration Values for ASP.NET Page Caching.

The following code example shows how to use the DisableExpiration property.

// Enable or disable cache expiration.
cacheSection.DisableExpiration =
    !cacheSection.DisableExpiration;
