In my portlet.xml I specified <cache-scope>PUBLIC</cache-scope> And I expect that the mark up is cached for all the users(per the portlet 2.0 spec). However it doesnt seem to be working that way. It just behaves as if cache-scope is set to PRIVATE. Here is the snippet from my portlet.xml <portlet> | <description>Content Portlet</description> | <portlet-name>ContentPortlet</portlet-name> | <portlet-class>com.public.portlet.ContentPortlet</portlet-class> | <supports> | <mime-type>text/html</mime-type> | <portlet-mode>view</portlet-mode> | </supports> | <portlet-info> | <title>Content Portlet</title> | </portlet-info> | <cache-scope>PUBLIC</cache-scope> | <expiration-cache>90</expiration-cache> | </portlet> Any thoughts/suggestions?
