Syntax
Remarks
For more information, go to RFC 2616: Hypertext Transfer Protocol -- HTTP/1.1, on the tp://go.microsoft.com/fwlink/?linkid=37125 Web site. In particular, for complete details, see Section 14.9 "Cache-Control" and Section 13, "Caching in HTTP."
NoCache does not send the common HTTP 1.0 request directive Pragma: no-cache.
Members
| Member Name | Description |
|---|---|
| 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 HttpCacheability.NoCache option. Clients receive a Cache-Control: no-cache directive but the document is cached on the origin server. Equivalent to HttpCacheability.ServerAndNoCache. |
| ServerAndNoCache |
Applies the settings of both HttpCacheability.Server and HttpCacheability.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. |
