+* If NiFi is running securely, configuration must be updated to allow
expected Host and context paths HTTP headers.
+
+** By default, NiFi will only accept HTTP requests with a Host header
matching the host[:port] that it is bound to. If NiFi is to accept requests
directed to a different
+host[:port] the expected values need to be configured. This may be
required when running behind a proxy or in a containerized environment. This is
configured in a comma
+separated list in _nifi.properties_ using the `nifi.web.proxy.host`
property. (e.g. localhost:18443, proxyhost:443)

The part about host headers is accurate -- it is only activated when
running securely, and this is the correct property to set.
