title: SEO friendly urls to avoid duplicate content
body: <p>I have nearly completed my .htaccess file now so that my urls all work properly. However i have a quick question: </p>
  
  <p>I have a rewirte that looks like this :</p>
  
  <pre><code>    RewriteRule ^fishing/([^/]*)/?$ region.php?region=$1 [L]  
  </code></pre>
  
  <p>This works in that if i type in fishing/fife/ it loads the region.php file. However what i didnt know nor expect was that if i type in region.php?region=fife then this also works. </p>
  
  <p>I believe that this will give me duplicated content and my SEO rating will be effected. How do i make is so that if i type in region.php?region=fife that it automatically changes to fishing/fife/ ????</p>
