WSRP two-phase rendering
The WSRP Consumer and the WSRP Producer in the portal support two-phase rendering for JSR 286 portlets. This allows a remote portlet to set headers and cookies and to modify the HTML head section. The WSRP Producer determines whether a JSR 286 portlet requires two-phase rendering and, if it does, the Producer invokes the render method in two phases.
Both the Producer and the Consumer can configure WSRP by using the following portal service configuration parameter in the portal Configuration Service:
wsrp.ignore.headers = (comma-separated list of headers)Use this parameter to specify one or more headers that should be ignored by WSRP when a portlet sets the header in the render headers phase. By default this parameter is not set.
The Producer does not pass any headers that are contained in this list to the Consumer, and the Consumer does not pass any headers that are contained in this list to the Producer.You can set this parameter in the portal Configuration Service by using the administrative console.
