Notice how no connect events are fired for the second call. It reused the connection from the first request for dramatically better performance.

### 3. Generate Self-contained Access Tokens

By default, a UUID is issued as an id_token in WSO2 Identity Server, which is of the first type above. But, it also can be configured to issue a self-contained id_token (JWT), which is of the second type above.

- Open the `<IS_HOME>/repository/conf/identity/identity.xml` file and uncomment the following entry under `<OAuth>` element.

```

    assertRoute(selection1.next(), address, proxyA, dns.lookup(PROXY_A_HOST, 1), PROXY_A_PORT)
    dns.assertRequests(PROXY_A_HOST)
    assertThat(selection1.hasNext()).isFalse()

    // Next try the IP address of the second proxy.
    assertThat(routeSelector.hasNext()).isTrue()
    dns[PROXY_B_HOST] = dns.allocate(1)
    val selection2 = routeSelector.next()

			client.doListen(ctx, listenCh, v)
			select {
			case <-ctx.Done():
				return
			default:
				// There was error in the REST request, retry after sometime as probably the peer is down.
				time.Sleep(5 * time.Second)
			}
		}
	}()
}

// Trace - send http trace request to peer nodes
func (client *peerRESTClient) Trace(ctx context.Context, traceCh chan<- []byte, traceOpts madmin.ServiceTraceOpts) {

        this.lastUpdateTime = createTime;
        this.lastAccessTime = createTime;
        this.maxAge = 30000; // 30 seconds default

        this.lock = new ReentrantReadWriteLock();
        this.isComplete = false;

#### Directory Structure { #directory-structure }

You should now have a directory structure like:

```
