I am trying to set up a two-layer proxy for public mobile devices,

I want an easy way for end-users to find out if their device is using
transparent or auto-detected settings, after they have connected to
the public wireless with no password.
The only way I can see for doing that is to have a splash page that
attempts an HTTPS connection when they first connect, using that to
find out if auto-detect worked or not. And if it fails, then I can
have a way to direct them to IT support to see what needs to be done
to get proxied access working.
When using squid for this you should have different http_port entries
in Squid for handling forward-proxy traffic (auto-detect worked) and
intercepted traffic (auto-detect failed).
You can use the http_port name= parameter and a myportname type ACL to
detect whether auto-detect worked before the splash page exists.
