title: How to keep database connect alive?
body: <p>I'm using ajax, and quite often if not all the time, the first request is timed out.  In fact, if I delay for several minutes before making a new request, I always have this issue.  But the subsequent requests are all OK.  So I'm guessing that the first time used a database connect that is dead. I'm using MySQL.</p>
  
  <p>Any good solution?</p>
