This is a very wise structure.

You then need to mess around a little with redirectors etc, and pray the
iNotes server never returns absolute URLs back to the client which it
almost certainly will do at some point..

The problem with such design is that the web server is unaware about the
externally used URLs and thinks it's URL name space is the way it is
strucured on the server. This shows up in in generated URLs and redirect
messages and will send the client to what your web server thinks is the
correct URL, not the URL you have assigned in the reverse proxy to the
server.
