The URL `http://www.publicobject.com/helloworld.txt` redirects to `https://publicobject.com/helloworld.txt`, and OkHttp follows this redirect automatically. Our application interceptor is called **once** and the response returned from `chain.proceed()` has the redirected response:

With rewrites, redirects, follow-ups and retries, your simple request may yield many requests and responses. OkHttp uses `Call` to model the task of satisfying your request through however many intermediate requests and responses are necessary. Typically this isn’t many! But it’s comforting to know that your code will continue to work if your URLs are redirected or if you failover to an alternate IP address.
