Debug Logging
OkHttp has internal APIs to enable debug logging. It uses the java.util.logging API which can be
tricky to configure. As a shortcut, you can paste OkHttpDebugLogging.kt. Then enable debug logging
for whichever features you need:
OkHttpDebugLogging.enableHttp2()
OkHttpDebugLogging.enableTaskRunner()
On Android, use OkHttpDebugLogcat.kt instead. It connects OkHttp logs to Logcat in Android Studio.
HTTP/2 Frame Logging
This logs inbound (<<) and outbound (>>) frames for HTTP/2 connections.
