When trying to produce a custom 404 error, I attempt to respond with responseFile notFound404 [("Content-Type","text/html")] "404.html" Nothing. However, if "404.html" is present in my filesystem, Warp sends the data with status code 200.
Is this behavior expected by servers that support the wai interface? If so, why does responseFile have a status argument?
It looks like a bug in Warp. Can you open an issue on the tracker?
