/logtail/<program> returns a 404 when inet_http_server run behind a reverse proxy, via a sub-path

[kartick]

1. Setup, and run nginx as reverse proxy, proxying to http://127.0.0.1:9001 and responding to requests coming on /supervisor (see attached config).
2. Fire up the browser and access http://127.0.0.1/supervisor (this will show the web UI correctly), links like stop, restart, work
3. Click the "Tail -f" link for any supervisor "program" listed on the UI -> Returns a 404
