The Cache Server

The cache server is the IP address of the actual transparent proxy cache server. Each cache server belongs to a server farm. You create a cache server by entering its IP address within the server farm configuration command mode. Once entered, you are placed in TWCB cache server configuration command mode.

Within TWCB cache server configuration command mode, you can select the type of fail detection that will be used by this cache server and set its parameters. Fail detection specifies the method that will be used by the router to determine whether the cache server is in an up or down state. Fail detection type can be set to ping, application TCP, or both. The application method defaults to a check of service availability on port 80. A non-standard HTTP port can be configured. The application method will use this configuration when checking service availability. Both the interval between retries and the number of retries for each method are configurable.

You can configure the maximum number of connections (bindings) allowed for this cache server.

Once a cache server is configured, you must place it in service and the cache server should be reporting that the server is “up” for the cache server to be active on the server farm.
