Planning for WSRP

Before you work with WSRP, plan your configuration based on the following information.

• Support statements
• Table to compare between WSRP V 1 and V 2.

How WSRP is implemented in the portal

• As a Producer, provide portlets as WSRP services for remote invocation by Consumers.
• As a Consumer, integrate WSRP services that are provided by Producers as remote portlets. On the Consumer portal these portlets behave like local portlets that comply with the standard portlet API, independent of their implementation on the Producer side - by the standard portlet API, the IBM portlet API, .NET, or other implementations.

At this time the WSRP Producer implementation in the portal does not support the Registration interface of the WSRP specification. This interface is optional. However, the Consumer portal can handle Producers that support WSRP registration interfaces.

Prerequisites for WSRP in the portal

If you want to use WSRP with your portal, have the appropriate level of IBM WebSphere Application Server installed. Refer to WebSphere Portal detailed system requirements to determine the WebSphere Application Server version that is required by your version of WebSphere Portal Express.

Exchanging the information required for WSRP

• The configuration of the Producer portal and its WSRP interfaces, and the location where the Consumer can find them.
• The security setup for WSRP on the Producer portal.

WSRP markup caching

The WSRP implementation in the portal uses expiry-based markup caching for remote portlets to improve performance. This reduces the number of interactions between the Consumer and the Producer and enables the use of remote caches for pages containing remote portlets.

For more information about markup caching refer to WSRP Markup Caching.

• Security considerations for WSRP services
  When you use WSRP with your portal, you can configure security and provide authentication by using different authentication mechanisms.
• How you work with WSRP in your portal
  To work with WSRP in your portal, you perform different administrative tasks. Some of these tasks depend on whether you use your portal as a Producer or Consumer portal.
• Communication between the Producer and Consumer portals
  The WSRP standard defines the communication interfaces between the Producer portal and the Consumer portal.
• Cookie support
  The WSRP Consumer stores cookies received from a Producer or from resources served by the WSRP Consumer as a proxy, and forwards the cookies appropriately in subsequent requests to a Producer or other resources.
