An appserver works with a Web server to handle requests for dynamic content, such as servlets, from Web apps. A Web server uses a Web server plug-ins to establish and maintain persistent HTTP and HTTPS connections with an appserver.

The Supported Hardware and Software Web page provides the most current information about supported Web servers.

Communicating with Web servers describes how to set up the Web server and Web server plug-in environment and how to create a Web server definition. The Web server definition associates a Web server with a previously defined managed or unmanaged node. After you define the Web server to a node, we can use the admin console to perform the following functions for that Web server.

If a Web server is defined to a managed node, we can:

If the Web server is an IBM HTTP Server and the IBM HTTP Server Administration server is installed and properly configured, we can also:

If the Web server is defined to an unmanaged node, we can:

We can not propagate an updated plug-in configuration file to a non-IBM HTTP Server that is defined to an unmanaged node. You must manually install an updated plug-in configuration file to a Web server that is defined to an unmanaged node. Web servers defined to an unmanaged node are typically remote Web servers. Remote Web servers are Web servers that are not located on the same machine as the WAS.

After you set up the Web server and Web server plug-in, whenever you deploy a Web app, specify a Web server as the deployment target that serves as a router for requests to the Web app. The configuration settings in plugin-cfg.xml for each Web server are based on the applications that are routed through that Web server. If the Web server plug-in configuration service is enabled, a Web server plug-in's configuration file is automatically regenerated whenever a new application is associated with that Web server.

Before starting the Web server, make sure we are authorized to run any Application Response Measurement (ARM) agent associated with that Web server.
