title: WWW and non-WWW URL. Two different sites
body: <p>I just noticed today that a website I am creating has the WWW or non-WWW problem.  If you go to http: //www.taskconductor.com, it is a different page with the same content as just http: //taskconductor.com.  </p>
  
  <p>If you were to login (username: show@412customs.com, Pass: tester) at http: //www.taskconductor.com, then try to go to http: //taskconductor.com (without the WWW), it will make you log in again.  Then as you can see, when you check your cookies, you can see that there are two sets of cookies.  One for http: //taskconductor.com and one for http: //www.taskconductor.com.  </p>
  
  <p>I have seen that this is a problem, but do I need to make a redirect? and if so, does it have to be index.php?  I would really prefer to have all of my main content on index.php.  </p>
  
  <p>How can I get around this?</p>
