# Frontend - receive http transfer as https
# It creates a frontend that listens on port 8881,
# sets x-forwarded-for and
# redirects all requests on HTTP to their equivalent on HTTPS
# 30 defines a frontend named www,
# 31 has it listen on port 8881,
# 32 has it insert x-forwarded-for: <client ip>,
# 33 redirects to the same location using https if the connection is not ssl
