WEB SERVERS

Setting up Domino to work with other Web servers
Back-end IBM® Lotus® Domino® 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 IBM® 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 server. The Domino 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 back-end 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 back-end Domino server can be on any supported operating system platform. The following front-end servers are supported:


You can download the Web server plug-in files for WAS from the IBM software downloads - Trials and demos Web site, 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, Domino Web Access, and Lotus Domino Off-Line Services (DOLS). Additional Domino products may also be supported; refer to the product documentation for details.
