Hi Xavier,

Yes — I’ll follow up with you off-list to collect the right logs from your 
machine.

Best,
Tommy

Well we are really looking forward some help. Because the good part was really 
fast captive portal window on devices.

Anyway will take the suggestion of Michael and will do some other tests.

We will be pleased to have any input we can have to fix that…

Kind regards,

Tommy probably knows what is going on.  Or at least can help with working it 
out.

Wow, thank you so much for doing this... I'm sorry that it caused problems...

The thing that I'm thinking about is ETag, Caching, etc. headers on the
replies.  I think that there should never be caching, but it feels like maybe
iOS is caching something.
I can't say if it's a bug or what.

I'm hoping we'll find soneone replying here about this, perhaps offering to
debug this with you.  (This might be a job for the IETF Hackathon
VPN... which does L2 stuff)
