+      <p>DNS resolution happens when the socket to
+        the origin domain is created for the first time.
+        When connection pooling is used, each backend domain is resolved 
+        only once per child process, and reused for all further connections 
+        until the child is recycled. This information should to be considered 
+        while planning DNS maintenance tasks involving backend domains. 
+        Please also check <code class="directive"><a href="#proxypass">ProxyPass</a></code>
+        parameters for more details about connection reuse.
