> Sucks that in hotels Firefox determines if there's a captive portal in effect by querying a Mozilla-hosted site (detectportal.firefox.com). But all browsers do this. "Windows performs a series of network tests. The destination site of these tests is msftncsi.com," https://docs.microsoft.com/en-us/windows-hardware/drivers/mobilebroadband/captive-portals https://docs.microsoft.com/en-us/windows-hardware/drivers/mo... "Shill, the connection manager for Chromium OS, attempts to detect services that are within a captive portal whenever a service transitions to the ready state. This determination of being in a captive portal or being online is done by attempting to retrieve the webpage http://clients3.google.com/generate_204 http://clients3.google.com/generate_204. This well known URL is known to return an empty page with an HTTP status 204. If for any reason the web page is not returned, or an HTTP response other than 204 is received, then shill marks the service as being in the portal state." https://www.chromium.org/chromium-os/chromiumos-design-docs/network-portal-detection https://www.chromium.org/chromium-os/chromiumos-design-docs/...
