> The NiFi Web Security Configuration includes a custom CORS Configuration Source that disallows HTTP POST requests for Template Uploads. The works as expected with direct access to the NiFi UI, but causes issues when attempting to upload a template to NiFi through a reverse proxy.
> When a web browser sends a template upload request that includes an unexpected {{Origin}} header, the Spring CORS Filter returns HTTP 403 Forbidden with a response body containing the message {{Invalid CORS Request}}.  NIFI-6080 describes a workaround that involves setting a different {{Origin}} header.  The current approach as implemented in NIFI-5595 should be evaluated for potential improvements to avoid this behavior when running NiFi with a reverse proxy.
