Safari 15 iOS Bypasses proxy.pac PROXY setting for HTTPS 400 code #21
Open
essandess opened 2 years ago
The PROXY blackhole approach used in this repo has stopped working for HTTPS requests on all iOS after updating to Safari on iOS/iPadOS 15.
Most requests now are HTTPS, so this breaks functionality.
Safari 15 appears to bypass the proxy.pac PROXY and sends requests to https://unwarranted.tracker.website/?whatever.
I hypothesize the reason is that the proxy returns 400 for such HTTPS CONNECT requests. Its behavior, expected for HTTPS CONNECT requests,looks like:
The fix appears to be to deprecate this repo and use Privoxy’s HTTPS inspection along with adblock2privoxy.
