Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
supports both synchronous blocking calls and async calls with callbacks.


Get a URL
---------

This program downloads a URL and prints its contents as a string. [Full source][get_example].

```java
OkHttpClient client = new OkHttpClient();

// Main main for minio server.
func Main(args []string) {
	// Set the minio app name.
	appName := filepath.Base(args[0])

	if env.Get("_MINIO_DEBUG_NO_EXIT", "") != "" {
		freeze := func(_ int) {
			// Infinite blocking op
			<-make(chan struct{})
		}

		// Override the logger os.Exit()
		logger.ExitFunc = freeze

		defer func() {
			if err := recover(); err != nil {
				fmt.Println("panic:", err)

It is connecting to the database and storing the connection data in an internal variable that is independent for each request (using the `contextvars` tricks from above).

Because the database connection is potentially I/O blocking, this dependency is created with a normal `def` function.

And then, in each *path operation function* that needs to access the database we add it as a dependency.

  public final double getRate() {
    synchronized (mutex()) {
      return doGetRate();
    }
  }

  abstract double doGetRate();

  /**
   * Acquires a single permit from this {@code RateLimiter}, blocking until the request can be
   * granted. Tells the amount of time slept, if any.
   *
   * <p>This method is equivalent to {@code acquire(1)}.
