Oracle Web Cache For Weblogic Server
Oracle Web Cache is the primary caching mechanism provided with Oracle Fusion Middleware. Caching improves the performance, scalability, and availability of Web sites that run on Oracle Fusion Middleware by storing frequently accessed URLs in memory.
By storing frequently accessed URLs in memory, Oracle Web Cache eliminates the need to repeatedly process requests for those URLs on the application Web server and database tiers. Unlike legacy proxies that handle only static objects, Oracle Web Cache caches both static and dynamically generated content from one or more application Web servers. Because Oracle Web Cache can cache more content than legacy proxies, it provides optimal performance by greatly reducing the load on application Web server and database tiers. As an external cache, Oracle Web Cache is also an order of magnitude faster than object caches that run within the application tier.
Because Web Cache is fully compliant with HTTP1.0 and 1.1 specifications, it can accelerate Web sites that are hosted by any standard Web servers, such as Apache Tomcat and Microsoft IIS. In Oracle Fusion Middleware, Oracle Web Cache resides in front of one or more instances of Oracle HTTP Server. Responses to browser based HTTP requests are directed to the Oracle HTTP Server instance and transmitted through Oracle Web Cache. The Oracle Web Cache instance can handle any Web content transmitted with the standard HTTP protocol.
