Caching
Caching Proxy's caching functionality helps to minimize network bandwidth utilization and ensure that end users receive faster, more reliable service. This is accomplished because the caching performed by the proxy server offloads back-end servers and peering links. Caching Proxy can cache static content and content dynamically generated by WebSphere® Application Server. To provide enhanced caching, Caching Proxy also functions in conjunction with the Application Server Load Balancer component. See Introducing WebSphere Application Server Edge components for an introduction to these systems.
IMPORTANT: Caching Proxy is available on all Edge component installations, with the following exceptions:
- Caching Proxy is not available for Edge component installations that run on Itanium 2 or AMD Opteron 64-bit processors.
- Caching Proxy is not available for Edge component installations of Load Balancer for IPv4 and IPv6.
