I&#39;ve spent the past day working on getting pound up and running and discovered a very cool new feature in 2.4 of setting TTL -1 to get a constant hash.<div><br></div><div>However, trying to use it was consistently hanging pound on the first request. &nbsp;In using HEADER based sessions, anything without the header would go through fine, but the minute a request with the header went through, pound would hang for good (not respond to any other subsequent requests).</div>
