title: redirect subdomain and retain url structure
body: <p>I'm redirecting a wordpress blog that lived in a subdomin to my root.  when i visit links from my old blog, they just redirect to the index page of my blog, but i need them to redirect to the actual post.  for example - </p>
  
  <pre><code>sub.mysite.com/1/2/3 - should redirect to -  mysite.com/sub/1/2/3
  </code></pre>
  
  <p>how can this be done?  thanks!</p>
  
  <p>UPDATE - still haven't found a solution for this.  Anyone?</p>
  
  <p>OR is there another post here that already exists that will show me the correct way to do this?  THANKS!</p>
