HTTP requests are no longer forwarded to TRIRIGA
After you upgrade TRIRIGA on WebSphere Application Server, IBM HTTP Server no longer forwards requests to TRIRIGA.
You must reconfigure the web server in WebSphere Application Server. One method of reconfiguring the web server is to use the WebSphere Customization Toolbox (WCT). WCT contains the Web Server Plug-ins Configuration Tool, which steps through the process of deleting and re-creating the web server definition for IBM HTTP Server.
Tip: When you specify the application server location in the Configuration Scenario Selection dialog, if your configuration scenario is local then browse to the location of the \AppServer folder. For example, a common location for the application server is C:\Program Files (x86)\IBM\WebSphere\AppServer.
If you change the host name, check the plugin-cfg.xml file to make sure that it contains the correct host name specified. Specifically, check the Transport Hostname property. The plugin-cfg.xml is typically in pathToInstall/IBM/HTTPServer/Plugins/config/webServerName/plugin-cfg.xml.
