Re: [Captive-portals] practicality of 511 HTTP status code

511 was defined with a fair dash of hope -- that someone would pick it up and run with it. 

It isn't complete; client behaviours need to be defined, probably through new media type(s) and/or HTTP response headers.

The nice thing about it is that its semantics are unambiguous; it's clear that you've got a response from the intervening network, NOT the endpoint you intended. That's helpful, especially for non-browser clients.
