Members are added to a balancer using

+ <div class="note"><h3>DNS resolution for origin domains</h3>
+ <p>The DNS domain resolution happens when the socket to
+ the origin server is created for the first time.
+ When connection pooling is used, the DNS resolution is performed
+ again only when the <code>ttl</code> of the connection expires
+ (please check <code class="directive"><a href="#proxypass">ProxyPass</a></code>
+ parameters).
+ This means that httpd does not perform any DNS resolution caching.
