In our system, when a user enables a mobile hotspot and the system connects to it, the system attempts to verify WIFI availability by sending an HTTP GET request to http://captive.apple.com.
Normally, the server returns:
HTTP Status: 200 (OK)
Content-Type: text/html
This has always been used as a sign of normal connectivity.
Issue: Since last Friday, the server sometimes responds with:
Content-Type: application/octet-stream
When this occurs, our system determines that the network is unavailable and displays a connection warning (a “!” icon).
Question: Has Apple recently made any backend or CDN configuration changes to captive.apple.com that could affect the response type?
Any advice how can we solve this problem?
Thanks!
