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()
```

### Activating on Android

```
$ adb shell setprop log.tag.okhttp.Http2 DEBUG

  val sslDebug: Boolean by option(help = "Output SSL Debug").flag()

  val url: String? by argument(name = "url", help = "Remote resource URL")

  var client: Call.Factory? = null

  override fun run() {
    LoggingUtil.configureLogging(debug = verbose, showHttp2Frames = showHttp2Frames, sslDebug = sslDebug)

    commonRun()
  }

 *  Fix: Don't fail on a redirect when a client has configured a 'trust everything' trust manager.
    Typically this would cause certain redirects to fail in debug and development configurations.


## Version 4.4.0

 *  New: Support `canceled()` as an event that can be observed by `EventListener`. This should be
