## Configuring Site Replication

- Configure an alias in `mc` for each of the sites. For example if you have three MinIO sites, you may run:

```sh
mc alias set minio1 https://minio1.example.com:9000 adminuser adminpassword
mc alias set minio2 https://minio2.example.com:9000 adminuser adminpassword

		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}
	if len(buckets) != 2 {
		t.Errorf("%s: Expected number of bucket to be `%d`, but instead found `%d`", instanceType, 2, len(buckets))
	}

	// add three and test exists + prefix.
	err = obj.MakeBucket(context.Background(), "bucket22", MakeBucketOptions{})
	if err != nil {
		t.Fatalf("%s: <ERROR> %s", instanceType, err)
	}

	// 1. Initiate 2 uploads for the same object
	// 2. Upload 2 parts for the second upload
	// 3. Abort the second upload.
	// 4. Abort the first upload.
	// This will test abort upload when there are more than one upload IDs
	// and the case where there is only one upload ID.

	// construct HTTP request to initiate a NewMultipart upload.
	request, err = newTestSignedRequest(http.MethodPost, getNewMultipartURL(s.endPoint, bucketName, objectName),

		},
	}

	jsonData := []byte(`{"three":true,"two":"foo","one":-1}
{"three":false,"two":"bar","one":null}
{"three":true,"two":"baz","one":2.5}
`)

	for i, testCase := range testTable {
		t.Run(fmt.Sprint(i), func(t *testing.T) {

	// Write the config input KV to history.
	err = saveServerConfigHistory(ctx, objectAPI, kvBytes)
	return
}

// GetConfigKVHandler - GET /minio/admin/v3/get-config-kv?key={key}
//
// `key` can be one of three forms:
// 1. `subsys:target` -> request for config of a single subsystem and target pair.
// 2. `subsys:` -> request for config of a single subsystem and the default target.

and other connections will be blocked while the large payload is being sent.

## Handlers & Routes

Handlers have a predefined Handler ID. 
In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

    by the users IAM policy.

    This is due to an issue of prefix based Matcher() function
    which was incorrectly matching prefix based on resource
    prefixes instead of exact match.
```

- There is always a possibility of a fix that is new, it is advised that the developer must make sure that the fix is sent upstream, reviewed and merged to the master branch.
