There may be many routes for a single address. For example, a webserver that is hosted in multiple datacenters may yield multiple IP addresses in its DNS response.

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

        // Each call should return a new instance
        assertNotSame(option1, option2);
    }

* Keep commits discrete. Avoid including multiple unrelated changes in a single commit.
* Keep commits self-contained. Avoid spreading a single change across multiple commits. A single commit should make sense in isolation.

### Testing changes

After making changes, you can test your code in 2 ways:

#### Run tests

A single HTTP call may require follow-up requests to be made to handle authentication challenges, redirects, and HTTP-layer timeouts. In such cases multiple connections, requests, and responses may be attempted. Follow-ups are another reason a single call may trigger multiple events of the same type.

        File file = cos.getFile();
        assertTrue(file.exists());
        cos.close();
    }

    @Test
    public void testMultipleWrites() throws IOException {
        // Multiple write calls should accumulate
        ContentOutputStream cos = new ContentOutputStream(10, Curl.tmpDir);
        cos.write(new byte[] { 0, 1, 2 });
        assertTrue(cos.isInMemory());

        assertSame(dataStore, dataStoreFactory.getDataStore("MYSTORE"));
        assertSame(dataStore, dataStoreFactory.getDataStore("mYsToRe"));
    }

    // Test multiple data store registration
    @Test
    public void test_multipleDataStores() {
        TestDataStore dataStore1 = new TestDataStore("Store1");
        TestDataStore2 dataStore2 = new TestDataStore2("Store2");
