This illustration shows application Web server failover. Several incoming requests for sites www.company.com:80 and www.server.com:80 enter Oracle Web Cache, which distributes the requests among appropriate application Web servers for the sites.

In this scenario, www.server.com:80 usually has three servers running, but server3-host has failed. Oracle Web Cache distributes the requests to the remaining operational application Web servers, server1-host and server2-host.
