Members| Member | Description |
|---|---|
| NSURLRequestUseProtocolCachePolicy | Specifies that the caching logic defined in the protocol implementation, if any, is used for a particular URL load request. This is the default policy for URL load requests. Available in Mac OS X v10.2 and later. |
| NSURLRequestReloadIgnoringLocalCacheData | Specifies that the data for the URL load should be loaded from the originating source. No existing cache data should be used to satisfy a URL load request. Available in Mac OS X v10.5 and later. |
| NSURLRequestReloadIgnoringLocalAndRemoteCacheData | Specifies that not only should the local cache data be ignored, but that proxies and other intermediates should be instructed to disregard their caches so far as the protocol allows. Available in Mac OS X v10.5 and later. |
| NSURLRequestReloadIgnoringCacheData | Replaced by NSURLRequestReloadIgnoringLocalCacheData. Available in Mac OS X v10.2 and later. |
| NSURLRequestReturnCacheDataElseLoad | Specifies that the existing cached data should be used to satisfy the request, regardless of its age or expiration date. If there is no existing data in the cache corresponding the request, the data is loaded from the originating source. Available in Mac OS X v10.2 and later. |
| NSURLRequestReturnCacheDataDontLoad | Specifies that the existing cache data should be used to satisfy a request, regardless of its age or expiration date. If there is no existing data in the cache corresponding to a URL load request, no attempt is made to load the data from the originating source, and the load is considered to have failed. This constant specifies a behavior that is similar to an “offline” mode. Available in Mac OS X v10.2 and later. |
| NSURLRequestReloadRevalidatingCacheData | Specifies that the existing cache data may be used provided the origin source confirms its validity, otherwise the URL is loaded from the origin source. Available in Mac OS X v10.5 and later. |
