+      <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.
