When the Cache Engine receives the request, it attempts to service the request from its own cache. If the requested information is not present, the Cache Engine contacts the Web server for it. After receiving this information from the Web server, the Cache Engine passes it back to the client and possibly caches it for use in fulfilling future requests. In addition to the technical documents and release bulletins available to all CCO users, contract holders are provided with a number of tools to facilitate the deployment of new releases. The new Cisco IOS Planner provides users with more flexibility to browse for their preferred software.
