How does OracleAS Web Cache support server load balancing and failover?
OracleAS Web Cache uniquely combines caching and load balancing in a single offering. Logically deployed between browser client and a Web server farm, OracleAS Web Cache intercepts all HTTP and HTTPS requests sent to the Web site and responds with a cached page if there is a valid version in the cache. All cache misses, whether cacheable or non-cacheable, are passed to the origin Web servers on the back-end. OracleAS Web Cache distributes these requests according to the relative capacity of each Web server. Web server capacity is configured by the OracleAS Web Cache administrator. Just as network load balancers do, OracleAS Web Cache can determine when a Web server has failed and then automatically redistribute the load over the remaining servers. When a Web server failure occurs, the cache periodically checks to see if the failed Web server has returned to a functional state and is capable of serving dynamically generated content. Layer 7 status checking, as this mechanism is called,
