Configuring a web server plug-in for Liberty

You can use the WebSphere plug-in with an Apache web server to route HTTP requests to applications that run in Liberty servers.

Before you begin

It is common to provide workload balancing and failover of application requests by running the same application in multiple application server processes, a pattern referred to as an application cluster. In such a topology, the web server plug-in must share the requests across all the application servers in the cluster, and it can be directed to do so by using a configuration that contains information about all of the application servers. This configuration is known as a merged plug-in configuration because it involves merging routing information from multiple application servers.

About this task

Liberty offers three ways to provide the merged plug-in configuration to the web server. Choose one of the following ways.

Procedure

Create the plug-in configuration for each application server, use a utility to merge these configurations into a single file, and then copy the file to the web server installation. This method can be used for Liberty servers from any edition of WebSphere; the servers do not need to be managed in a Liberty collective.
