WEB SERVERS
Setting up Domino to work with other Web servers
Back-end Domino 6 servers can receive, and respond to, requests from front-end IBM HTTP Servers (IHS) or from Microsoft Internet Information Servers (IIS). For this communication to occur, the appropriate WebSphere Application Server (WAS) 4.0.3 or later plug-in must be installed on the front-end server. These plug-ins recognize HTTP requests for Domino applications and pass them along to the Domino server. Other HTTP requests will be handled by the front-end server itself.

A typical scenario is for the front-end server to be outside a firewall. The front-end server receives requests from Web users, the plug-in relays the requests over HTTP, through the firewall, to the HTTP task on the back-end Domino 6 server. The Domino 6 server then processes the request and sends the reply back to the plug-in, which relays it to the user.

A plug-in can be configured to support any number of backend servers. Since Domino uses the same plugins as WebSphere, you can also combine Domino and WebSphere servers. For example, a Domino server hosting a mail application and a WebSphere server hosting a J2EE application could both be placed behind the same IIS front-end server.

The backend Domino server can be on any supported operating system platform. The following front-end servers are supported:

IBM HTTP Server on AIX, Windows NT 4.0, and Windows 2000 Server.

Microsoft IIS on Windows NT 4.0 and Windows 2000 Server.

The plug-in files are packaged with the Domino 6 server and their use is covered by your Domino license. You do not need to install any other WebSphere components to use the Microsoft IIS plug-in. However, to use the IHS plug-in you must install the IHS components of WebSphere on the front-end server.

The following features are supported for the Domino back-end servers: core Domino database functionality, Lotus iNotes Web Access, Lotus Domino Off-Line Services (DOLS), Lotus Discovery Server(TM). Additional Domino products may also be supported; refer to the product documentation for details.
