Usage

From source file:co.paralleluniverse.fibers.dropwizard.FiberHttpClientBuilder.java

/**
 * Add strategies to client such as ConnectionReuseStrategy and KeepAliveStrategy Note that this

protected void setStrategiesForClient(HttpAsyncClientBuilder client) {
    final long keepAlive = configuration.getKeepAlive().toMilliseconds();

    // don't keep alive the HTTP connection and thus don't reuse the TCP socket
    if (keepAlive == 0) {
        client.setConnectionReuseStrategy(new NoConnectionReuseStrategy());
    } else {
        client.setConnectionReuseStrategy(new DefaultConnectionReuseStrategy());
        // either keep alive based on response header Keep-Alive,
        // or if the server can keep a persistent connection (-1), then override based on client's configuration
        client.setKeepAliveStrategy(new DefaultConnectionKeepAliveStrategy() {
