I'm getting the infamous NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802) error on iOS 9.
I don't want to add a global exception but for specific domains.
How do I know which URL causes this error?

When your NSURLConnection or NSURLSessionTask error handling delegate method is called, obtain the URL from the request object and print it with NSLog (or just put a debug breakpoint in that method).
Or set the CFNETWORK_DIAGNOSTICS environment variable to 1 (or 2 or 3) if your code isn't making the request directly (e.g. if a third-party library is doing it on your behalf).

You can set CFNETWORK_DIAGNOSTICS environment variable as @dgatwood suggested or you can call setenv("CFNETWORK_DIAGNOSTICS", "3", 1);, for example, in main.m file. Once you have done any of options you should see appropriate message in console log:
2014-10-28 14:23:37.115 QTestbed[2626:60b] CFNetwork diagnostics log file created at: /private/var/mobile/Applications/76531F40-3291-4565-8C75-0438052C83BC/Library/Logs/CrashReporter/CFNetwork_com.example.apple-samplecode.QTestbed_2626.nwlrb.log
Just open this file after some time of usage of your app and check logs there.
Here is a link to the related Apple's Q&A.
