This feature is used by IBM WebSphere Portal to stop processing the same Action request twice (for example, browser Back button feature).
wps.multiple.action.execution is a portlet initialization parameter that can be set in the portlet’s deployment descriptor (that is, portlet.xml).
If this protection feature is left on (wps.multiple.action.execution=true), WebSphere Portal would treat a repeated Action URL as a Render URL with no repetition of portlet action, rather portlet would just be rendered.
This is achieved by storing executed Action results and state in a session to prevent the multiple actions.
