To prestuff content is to cache the content before it is explicitly requested by a client. By prestuffing content on an edge server, you can reduce the load on an origin server and decrease the latency experienced by clients. For example, to minimize bandwidth use during peak hours, a server administrator can cache streams during off-peak hours. For more information, see Downloading Content.
The following diagram illustrates a possible prestuffing scenario, and the numbers in the diagram correspond to the following steps:
The administrator copies content from the origin server to the cache proxy server.
The client, configured to specify P1 as a cache proxy server, requests content from the origin server.
The cache proxy server determines that it has the requested content in a local cache and streams it from the cache to the client.
