Transparent Cache Deployment 41
Figure 7 Deploying the Webcache and Server Load Balancer Together
The Webcache is directly connected to a SuperStack 3 Server Load
Balancer via the LAN port to improve the scaling and performance of a
group of web servers. The Server Load Balancer partitions network traffic
between a group of Web servers offering services to client machines. You
should primarily choose this deployment mode if you want to offload
traffic from Web servers to the Webcache(s).
You can attach one or more Webcaches to the Server Load Balancer and
assign them to particular load balancing services provided by the Web
servers. The Server Load Balancer can be configured to redirect Web
requests on TCP port 80 to a Webcache for a particular service, or to load
balance between multiple Webcaches based on standard load balancing
algorithms.
For further information about configuring the Server Load Balancer, refer
to the documentation that accompanies the device.
Web Cache
Communication
Protocol (WCCP)
The Web Cache Communication Protocol (WCCP) allows the Webcache
to be connected to one or more WCCP-enabled Cisco routers in your
network. The router automatically redirects all Web requests on TCP port
80 or FTP requests to the Webcache. Therefore no configuration of the
Web browser on each client machine is needed.
There are two versions of WCCP, known as WCCP V1 and WCCP V2,
which require different deployment methods. WCCP V1 allows a single
