Safari in iOS 15 keeps asking for providing a client certificate for each request
Our internal Web site is protected by a client certificate authentication.
Safari in iOS 15 keeps asking to provide a client certificate for each request. These certificates were installed via a configuration profile into an iPhone.
It is very annoying as a web side sends asynchronous calls frequently and therefore I'm asked to provide a certificate for each call.
This was not the case in iOS 14. In iOS 14, I have been asked to provide a client certificate for the first request only. Other subsequent requests till the session expiration were done with the same certificate without asking.
This seems to me like a bug in iOS 15.
Setup: iPhone 11, iOS 15.0.1
