title: Hash # tag for SEO and Mod Rewrite
body: <p>My objective is to use the hash # tag to help making web pages canonical. I've already implemented the canonical meta tag but our SEO expert says it will be even better with the # tag for pages which are not index by browsers, search engines that does not yet support the canonical meta tags etc.</p>
  
  <p>My plan is to insert the hash tag in our public urls: 
  <code>www.mysite.com?id=456</code> will become <code>www.mysite.com#?id=456</code></p>
  
  <p>I then plan to use Apaches mod_rewrite to replace #? with ? to render the URL usable for the web server.</p>
  
  <ul>
  <li>Question 1: How can this be done using mod_rewrite? Is it a simple
  operation? </li>
  <li>Question 2: Will this work as I intend it too?</li>
  </ul>
  
  <p>I'm using #? and not just # to avoid conflicts with potential anchors in the URL.</p>
