efficiently makes your stuff load faster and saves bandwidth.

OkHttp is an HTTP client that’s efficient by default:

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).
 * Transparent GZIP shrinks download sizes.
 * Response caching avoids the network completely for repeat requests.

        String msg = "\u00A1\u00A2"; // same Unicode string
        byte[] asciiBytes = msg.getBytes(SmbConstants.DEFAULT_OEM_ENCODING);
        assertTrue(asciiBytes.length > 0, "ASCII encoding should produce bytes");
    }

    @Test
    public void testBufferCreation() throws UnsupportedEncodingException {
        byte[] dataBytes = { 1, 2, 3, 4 };
        String params = "test";

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

   * is unnecessary; for example, {@code copyOf(copyOf(anArrayList))} will copy the data only once.
   * This reduces the expense of habitually making defensive copies at API boundaries. However, the
   * precise conditions for skipping the copy operation are undefined.

 * **RealConnectionPool** manages reuse of HTTP and HTTP/2 connections for reduced latency. Every OkHttpClient has one, and its lifetime spans the lifetime of the OkHttpClient.
