CacheControlHeaderValue.NoCache Property (System.Net.Http.Headers)

Remarks This property represents the “no-cache” directive in a cache-control header field on an HTTP request or HTTP response. When the NoCache property is set to true present in a HTTP request message, an application should forward the request toward the origin server even if it has a cached copy of what is being requested.
