Add hostname to footer in load-balanced configuration

From Chip:

Now that we're deploying load balanced XNAT instances, it would be useful, especially when having a problem, to be able to identify which backend XNAT host is being utilized.

Is it possible to make visible on the footer of XNAT pages which host the user is connected to?

This can be determined by checking the XNAT node info configuration against the hostname. There should also be a preference setting to force hostname display in cases where the nodes may configured oddly.
