<p>The present invention relates to a method and an apparatus for setting an upstream server in a network environment which provides content by using a multi-stage cache server. In a network environment, where at least one another cache server exists between the cache server and an original web server, an upstream server for the cache server is set. When a request for the content is received, upstream server setting information including at least one upstream server address is acquired from the request, and the received request is delivered to an upstream server corresponding to the server address acquired from the upstream server setting information.</p> |
