Ask Different is a question and answer site for power users of Apple hardware and software. It's 100% free, no registration required.

I'm an engineer developing a captive portal system for use at hotels. I know Apple devices do captive portal detection upon joining a wireless network to see if the user is behind a captive portal by attempting to load http://www.apple.com/library/test/success.html. If this URL does not load, or is redirected, the device assumes it is behind a captive portal and loads up the terms or login page in a websheet browser.

The problem is that we are properly redirecting these requests, but no Apple devices I test with present the websheet browser. I'm wondering if we need to provide a wispr response, or some additional information. Has anyone else had experience with this?
