The TWCB Binding

A TWCB binding has three devices associated with it: a client that initiates a service request, the destination device that responds to the service request, and a cache server that caches the response data. Each binding is based upon the following criteria:

• Source IP Address - The client IP address
• Destination IP Address - The IP address of the destination device
• Destination Port - The Destination Device Port
• Cache Server IP Address - The IP address of the cache server

TWCB matches bindings based upon the following four tuples: TCP protocol, source IP address, destination IP address, and destination web cache HTTP port value. Use the show ip twcb bindings or show ipv6 twcb bindings command to display active TWCB bindings for this device.
