Configure your IBM HTTP Server or Lotus Notes Domino HTTP Server to use either Web server with WebSphere Application Server for i5/OS.
Decide which HTTP Server you want to use to serve requests to WebSphere Application Server. For V6.1, the following Web servers are supported on i5/OS:
The IBM HTTP Server (original) is not supported for WebSphere Application Server. However, you can use the i5/OS IBM HTTP Server (Powered by Apache) with your application server. Or, you can configure a remote HTTP server residing on a supported platform to route requests to WebSphere Application Server running on the i5/OS server. Review Selecting a Web server topology diagram and roadmap for guidance.
An HTTP server instance is not required to install or use WebSphere Application Server. However, IBM recommends to support requests for servlets and JavaServer Pages resources managed by WebSphere Application Server.
