Configure portlet fragment caching
After a portlet is invoked and completes generating the output
to cache, a cache entry is created, containing the output and the side effects
of the portlet. These side effects can include calls to other portlets or
metadata about the entry, including timeout and entry priority information.
Configure portlet fragment caching with the WebSphere Application Sever administrative
console to save the output of portlets to the dynamic cache.
To enable portlet fragment caching, complete Enabling the dynamic cache service .
Overview
Unique entries are distinguished by an ID string that generates
from the PortletRequest object each time the portlet runs. You can then base
portlet fragment caching on:
- Request parameters and attributes
- Session information
- Portlet-specific information, portlet session, portlet window ID, portlet
mode, and portlet window state
Procedure
- In the administrative console, click Servers > Application
servers > server_name > Portlet container settings > Portlet
container in the administrative console navigation tree.
- Select Enable portlet fragment cache under the Configuration
tab.
- Click Apply or OK.
- Restart WebSphere Application Server.
See Managing application servers for
more information.
What to do next
Define the cache policy for your portlets by Configuring cacheable objects with the cachespec.xml file.
