What's New in Oracle Web Cache?

The new features for Oracle Web Cache in release 2.0 include:

• Edge Side Includes (ESI)

  ESI is a simple markup language that enables content assembly of dynamic HTML fragments. It provides for assembly by enabling Web pages to be broken down into fragments of differing cacheability profiles. Each fragment is a separate object with its own cacheability rule.

• Secure Sockets Layer (SSL) Support

  In addition to HTTP protocol requests, Oracle Web Cache is able to cache pages for HTTPS protocol requests.

• Cacheability Selectors

  In addition to a document's URL, cacheability can also be evaluated against a document's HTTP request method or the body of an HTTP POST method.

• Cacheability Attributes in HTTP Response Messages

  Application developers can add some of the cacheability attributes to the header of an HTTP response message for a document. This feature enables the application Web server to override the settings configured through the Oracle Web Cache Manager interface, as well as allowing other third-party caches to use Oracle Web Cache cacheability attributes.

• Cache Status Information in HTTP Response Messages

  Cache hit and cache miss information is added to the Server response-header field of the HTTP response message. This feature enables you to determine whether a request was served from the cache or the application Web server.

• Improved Invalidation

  Invalidation messages can be based on the exact URL that includes the complete path and file name or more advanced invalidation selectors. Advanced selectors include the URL prefix, HTTP request method, cookie, and HTTP request header.
