HttpCacheRevalidation Enumeration

.NET Framework 4.5

Provides enumerated values that are used to set revalidation-specific Cache-Control HTTP headers.

Namespace: System.Web

public enum HttpCacheRevalidation

	Member name	Description
	AllCaches	Sets the HTTP header to Cache-Control: must-revalidate.
	ProxyCaches	Sets the HTTP header to Cache-Control: proxy-revalidate.
