7.1 About Oracle Web Cache

Oracle Web Cache is a content-aware server accelerator, or reverse proxy server, that improves the performance, scalability, and availability of Web sites. By storing frequently accessed pages in memory, Oracle Web Cache eliminates the need to repeatedly process requests for those pages on middle-tier servers and databases. You can also use Oracle Web Cache for load balancing a multiple-machine installation. For more information, see Chapter 6, Managing Discoverer in a Multi-Machine or Multi-Instance Environment. You manage Oracle Web Cache using Oracle Enterprise Manager Fusion Middleware Control. To view Oracle Web Cache pages in Fusion Middleware Control: 1. Display the Oracle Fusion Middleware Control Home page. For more information, see Section 4.1.2, How to start Fusion Middleware Control and display the Farm Home page.

2. Navigate to the Web Cache node under the Web Tier node in the navigation pane.

Oracle Web Cache sits in front of application Web servers, caching their content and providing that content to Web browsers that request for the content. When Web browsers access the Web site, they send HTTP protocol or HTTPS protocol requests to Oracle Web Cache. Oracle Web Cache, in turn, acts as a virtual server to the application Web servers. If the requested content has changed, Oracle Web Cache retrieves the new content from the application Web servers. 7-2 Oracle Fusion Middleware Configuration Guide for Oracle Business Intelligence Discoverer Figure 7–1 Oracle Web Cache overview For more information about Oracle Web Cache, see Oracle Fusion Middleware Administrators Guide for Oracle Web Cache.
