Well that sucks. I believe a more correct response would have been 407Proxy Authentication Required, but the vendor probably wanted a “prettier” login screen. > Is there an established practice or set of documents on the iOS Dev Lib that > shows how to handle this?

Presumably the firewall sent back a redirect to the original response, which pointed to its magic login page. So that’s one way to tell something’s up. Another is that the Content-Type for the end response is text/html instead of application/json. I don’t know if there’s any de-facto standard for being able to detect firewall/router login pages. iOS and Lion seem to be able to do it. I heard something about a recent proposed standard for logins to WiFi hot-spots, which may or may not be relevant. This question is more relevant to the macnetworkprog list. I would recommend reposting it there. —Jens
