[V5.1 and later]Welcome to Web servers

In the WebSphere Application Server product, an Application Server works with a Web server to handle requests for Web applications. The Application Server and Web server communicate using a WebSphere HTTP plug-in for the Web server.

If you specify a Web server when installing the WAS product, the installation program changes the Web server configuration file automatically to establish a plug-in.

You do not need a Web server plug-in or Web server to start the application server or the administrative console. In a test or development environment, you can use the internal HTTP transport instead of the Web server plug-in and Web server. But, for performance reasons, use a Web server plug-in and Web server in a production environment.

The WAS documentation provides information on plug-ins but does not provide information on administering Web servers. To learn how to administer your Web server, refer to documentation for your Web server. For tips on tuning your Web server see Web server tuning parameters.
