Some tests by @LucasWerkmeister using webservice 0.66 and the --canonical switch indicated that nginx-ingress is returning HTTP 301.
This has some consequences:
- the tool developer cannot easily revert the redirect once it has been introduced. We should use HTTP 307 instead, so the --canonical switch can be reverted.
- firefox translated POST request to GET. Not sure if this is related to the HTTP 301 or that we need some special case for requests other than GETs
