Problems with IBM HTTP Server, WebSphere Plugin, WebSphere Application Server and Virtual Hosts

I was trying to resolve an issue whereby requests for Business Space ( part of IBM Business Monitor ) weren't being routed from IBM HTTP Server via the WebSphere Plugin to WebSphere Application Server

To find out what was going, I changed the error level in the Plugin configuration file: -

/opt/IBM/WebSphere/Plugins/config/webserver/config/webserver/plugin-cfg.xml

from: -

   <Log LogLevel="Error" Name="/opt/IBM/WebSphere/Plugins/logs/webserver/http_plugin.log"/>

to: -

   <Log LogLevel="Debug" Name="/opt/IBM/WebSphere/Plugins/logs/webserver/http_plugin.log"/>

and, having restarted IHS, I saw: -

Guess what the problem is ?

Yep, you've guessed it - I'd forgotten to add a Virtual Host entry for WAS for the required port - 8443.

I made, and saved, the change, synchronised the WAS nodes, restarted the appropriate JVM ( the WebApp cluster ), and voila, Business Space can now be accessed via IHS/Plugin: -
