Assembly: System.Web (in System.Web.dll)
The values for Private, Public, and No-Cache are strings and must be enclosed in quotation marks (" "). If the property is set to a value that does not match one of the HttpCacheability enumeration values, then an ArgumentException is thrown. If the property is not set, the cacheability of the response is set to NoCache.
The CacheControl, Expires, and ExpiresAbsolute properties have been deprecated. Instead, the methods of the HttpCachePolicy class are available through the Cache intrinsic object to control the Internet Information Services (IIS) output cache and client caches.
