### Holding multiple locks

You're allowed to take the Http2Connection lock while holding the Http2Writer lock. But not vice-versa. Because taking the Http2Writer lock can block.

In limited situations OkHttp will retry a route if connecting fails:

 * When making an HTTPS connection through an HTTP proxy, the proxy may issue an authentication challenge. OkHttp will call the proxy [authenticator](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) and try again.

    @Input
    public String getUrl() {
        return url;
    }

    @TaskAction
    public void verify() {
        getLogger().quiet("Verifying URL '{}'", url);

        // verify URL by making a HTTP call
    }
}

// Otherwise the name is interpreted as a case-insensitive unqualified
// identifier such as "errorf". Either way, if a listed name ends in f, the
// function is assumed to be Printf-like, taking a format string before the
// argument list. Otherwise it is assumed to be Print-like, taking a list
// of arguments with no format string.
