<p class="MsoNormal" style="margin-left:35.4pt"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">I am wondering if it is possible for the dispatcher module to monitor multiple endpoints that resolve from a single hostname
using DNS. Can I configure a single DNS name in the dispatcher table which resolves to 3 IP addresses and have them monitored by OPTIONS pings, and then select the first one that is marked as active to route requests to? I haven’t found much help online to
know if this is possible/supported.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:35.4pt"><span lang="EN-GB" style="font-size:10.0pt;font-family:"Verdana",sans-serif;color:#1F497D">i.e. Does the dispatcher module support monitoring of multiple results returned from DNS NAPTR records?<o:p></o:p></span></p>
