Cache-control directives are a way for Sun Java System Web Server to control what information is cached by a proxy server. Using cache-control directives, you override the default caching of the proxy to protect sensitive information from being cached, and perhaps retrieved later. For these directives to work, the proxy server must comply with HTTP 1.1.
For more information HTTP 1.1, see the Hypertext Transfer Protocol--HTTP/1.1 specification (RFC 2068) at:
From the virtual server page, click the Content Handling tab.
Click General sub tab and go to Cache Control Directives field under Miscellaneous section.
Fill in the fields. Valid values for the response directives are as follows:
Public. The response is cachable by any cache. This is the default.
Private. The response is only cachable by a private (non-shared) cache.
No Cache. The response must not be cached anywhere.
No Store. The cache must not store the request or response anywhere in nonvolatile storage.
Must Revalidate. The cache entry must be revalidated from the originating server.
Maximum Age (sec). The client does not accept a response that has an age greater than this age.
For setting cache control directives through CLI, execute the following command.
wadm> set-cache-control-directives --user=admin --password-file=admin.pwd --host=serverhost --port=8989 --config=config1 --vs=config1_vs_1 public=true private=true must-revalidate=true
