within ConnMan we decided to go for a vendor-header with a specific
value within the HTTP response. That way we are keeping the HTTP
response code and don't have to define a magic one.

In addition if you look at the big picture with actually integrating
WISPr, you do wanna make the initial request without HTTPS since you
need to figure out the login details first.

Also with 6to4 and all the other IPv6 setup magic, we separate IPv4
checks from IPv6 checks.
