Web Redirection for Caching

摘要

This specification generally relates to using redirect messages to implement caching. One example method includes receiving from a client a first request for a network resource, the first request including an original location of the network resource; determining that a response to the first request is to be cached; sending a redirect response to the client including a cache location for the network resource; receiving a second request for the network resource from the client, the second request including the cache location; in response to receiving the second request for the network resource from the client: determining that the network resource has not been previously cached; retrieving the network resource from the original location; caching the retrieved network resource in a location associated with the cache location for the network resource; and sending the retrieved network resource to the client.

receiving from a client a first request for a network resource, the first request including an original location of the network resource; determining that a response to the first request is to be cached; in response to determining that the response to the first request is to be cached, sending a redirect response to the client including a cache location for the network resource; receiving from the client a second request for the network resource, the second request including the cache location; in response to receiving the second request from the client for the network resource:
determining that the network resource has not been previously cached;retrieving the network resource from the original location;caching the retrieved network resource in a storage associated with the cache location for the network resource; andsending the retrieved network resource to the client.
