WebResponse.IsFromCache Property

Note: This property is new in the .NET Framework version 2.0.

Gets a Boolean value that indicates whether this response was obtained from the cache.

Namespace: System.Net
Assembly: System (in system.dll)

public virtual bool IsFromCache { get; }
/** @property */
public boolean get_IsFromCache ()

public function get IsFromCache () : boolean

Property Value

true if the response was taken from the cache; otherwise, false.

The current cache policy and the presence of the requested resource in the cache determine whether a response can be retrieved from the cache. Using cached responses usually improves application performance, but there is a risk that the response in the cache does not match the response on the server. Use the RequestCacheManager and RequestCachePolicy classes to set caching policy.
