The DLS relies on the HttpFS service with the domain name dls.httpfs.wa.bl.uk, which is hard-coded within DLS to refer to Nellie's 194. IP address. The firewall is set up along this route.
The monitor system should check that the relevant HttpFS service is running port 14000. Note also that our patched version of HttpFS has been modified so that the Content-Length is declared. Ideally we should also check for that, in case we 'downgrade' by accident at some point in the future.
