Example 7 with ProxyHandler

use of io.undertow.server.handlers.proxy.ProxyHandler in project keycloak by keycloak.

the class AbstractAdapterClusteredTest method prepareReverseProxy.

@Before
public void prepareReverseProxy() throws Exception {
    loadBalancerToNodes = new LoadBalancingProxyClient().addHost(NODE_1_URI, NODE_1_NAME).setConnectionsPerThread(10);
    // 1 hour for proxy request timeout, so we can debug the backend keycloak servers
    int maxTime = 3600000;
    reverseProxyToNodes = Undertow.builder().addHttpListener(HTTP_PORT_NODE_REVPROXY, ServerURLs.APP_SERVER_HOST).setIoThreads(2).setHandler(new ProxyHandler(loadBalancerToNodes, maxTime, ResponseCodeHandler.HANDLE_404)).build();
