      <note><title>DNS resolution for origin domains</title>

      <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 <directive module="mod_proxy">ProxyPass</directive>

        parameters).

        This means that httpd does not perform any DNS resolution caching.

        </p>
