Only content received using the System.Net.WebRequestMethods.Ftp.DownloadFile command is cached.

The following table describes the effects of FTP caching policies on System.Net.FtpWebRequest.


System.Net.Cache.RequestCacheLevel.Default	Returns the cached resource if the resource is fresh, the content length is accurate, and the expiration, modification, and content length attributes are present.
System.Net.Cache.RequestCacheLevel.BypassCache	Returns the resource from the server.
System.Net.Cache.RequestCacheLevel.CacheOnly	Returns the cached resource if the content length is present and matches the entry size; otherwise, throws a System.Net.WebException.
System.Net.Cache.RequestCacheLevel.CacheIfAvailable	Returns the cached resource if the content length is provided and matches the entry size; otherwise, the resource is downloaded from the server and is returned to the caller.
System.Net.Cache.RequestCacheLevel.Revalidate	Returns the cached resource if the timestamp of the cached resource is the same as the time stamp of the resource on the server; otherwise, the resource is downloaded from the server, stored in the cache, and returned to the caller.
System.Net.Cache.RequestCacheLevel.Reload	Downloads the resource from the server, stores it in the cache, and returns the resource to the caller.
System.Net.Cache.RequestCacheLevel.NoCacheNoStore	If a cached resource exists, it is deleted. The resource is downloaded from the server and is returned to the caller.

Note:

Setting FtpWebRequest.DefaultCachePolicy overrides any configuration setting.
