Assembly: System.Web (in system.web.dll)
|NoCache||Sets the Cache-Control: no-cache header. Without a field name, the directive applies to the entire request and a shared (proxy server) cache must force a successful revalidation with the origin Web server before satisfying the request. With a field name, the directive applies only to the named field; the rest of the response may be supplied from a shared cache.|
|Private||Default value. Sets Cache-Control: private to specify that the response is cacheable only on the client and not by shared (proxy server) caches.|
|Public||Sets Cache-Control: public to specify that the response is cacheable by clients and shared (proxy) caches.|
|Server||Specifies that the response is cached only at the origin server. Similar to the NoCache option. Clients receive a Cache-Control: no-cache directive but the document is cached on the origin server. Equivalent to ServerAndNoCache.|
|ServerAndNoCache||Applies the settings of both Server and NoCache to indicate that the content is cached at the server but all others are explicitly denied the ability to cache the response.|
|ServerAndPrivate||Indicates that the response is cached at the server and at the client but nowhere else. Proxy servers are not allowed to cache the response.|

NoCache does not send the common HTTP 1.0 request directive Pragma: no-cache.
