72 Partial-Page Caching and Page Assembly

Using configurable caching rules, Oracle Application Server Web Cache can cache static, dynamic, and partial pages.

For partial-page caching, OracleAS Web Cache supports the Edge Side Includes (ESI) standard. ESI and JESI (ESI for Java) are a set of XML and JSP tags that application developers use to identify cacheable and non-cacheable content fragments for page assembly in OracleAS Web Cache.

ESI uniquely identifies common elements that different, personalized Web pages share, and OracleAS Web Cache only caches or invalidates one copy of each element. This saves resources across all layers of a Web site’s infrastructure.
