Cache Policy

Cache Policy

Cache policy indicates what action a cache proxy server must take in response to a client request for content. Cache proxy plug-ins define cache policy for a Windows Media server. The policy differs depending on whether the requested content is found in a cache. If it is found, the cache proxy plug-in can direct the server to:

• Stream the content from cache on demand.
• Proxy broadcast content from the origin server.

If the content is not cached, or if it is out of date, the cache proxy plug-in can direct the server to:

• Proxy the content on demand from the origin server.
• Proxy the content as a broadcast from the origin server.
• Redirect the client to another origin server but still use the same proxy server.
• Redirect the client to a different proxy server.
• Download the requested content into cache while it is streaming the content to the client.

You can control what policies your custom cache proxy plug-in supports.
