title: How to rewrite `example.com/some/directory/path` to `archive.example.com/some/directory/path`
body: <p>Working on a site redesign. In the meantime, I've built a landing page at <code>example.com</code> and moved the original site to <code>archive.example.com</code>.</p>
  
  <p>I'd like all url's with a path to redirect to the archived site and retain the path.</p>
  
  <p><code>example.com/any/directory/path</code> -> <code>archive.example.com/any/directory/path</code></p>
  
  <p>Obviously I don't want <code>example.com</code> to redirect.</p>
  
  <p>Update: I also need <code>example.com/admin</code> to <em>not</em> redirect</p>
