> In AccessResource there is a method getNiFiUri() which returns a url that ends with "/nifi". Jetty has a requirement that a context path must end in a trailing /, and if it does not it will redirect to the url with the / (i.e. /nifi/). In most cases this is fine and no one will notice the Jetty redirect, but if you are behind a proxy, the Jetty redirect does not consider proxy related headers, so the redirect may land you at a host/port that is the local nifi host/port, and not through the proxy which will likely cause problems.
