title: Vanity Url in Joomla and jomsocial
body: <p>I know that jomsocial allows the following vanity urls to exist</p>
  
  <p>domain.com/profile/jack</p>
  
  <p>while this isnt strictly a vanity url the guys at jomsocial say it would be too intensive for performance to make this happen.</p>
  
  <p>ok well could a clever regular expression convert at least </p>
  
  <p>domain.com/jack to domain.com/profile/jack ? so that it works for every single profile that may get created, so it has to be clever and use variable 'username', in this case 'jack'</p>
  
  <p>How do other frameworks address the routing for this is it modrewrite ? is it php etc....</p>
  
  <p>thanks for any ideas or even the solution.</p>
