Caching pages shared by multiple users
If you use a proxy server such as WebSphere Edge Server and your system has content that can be shared among multiple users, you can improve performance by caching this shared content.
WebSphere® Portal allows you
to configure the cache scope and the cache expiry time of the specified
content. The cache scope and cache expiry time are configured by page,
portlet, and theme. WebSphere Portal combines
this information to produce a final cache scope and expiry time for
each page it serves. You can configure these cache settings in one
of the following two ways:
- The XML configuration interface
- See the XML configuration interface for information.
- Portlets
- The Manage Pages, Manage Portlets, and Properties portlets allow
you to configure cache settings. For detailed information, refer to
the portlet helps.Note: When caching JSR portlets, the cache scope is only for proxy server caching policies and requires the use of an edge server cache. Local display caching policies are not affected by this setting. The cache expiration setting is used for both local and remote caching policies.
