title: mod_rewrite with spaces in the urls
body: <p>I need to set up some RewriteRules to redirect a URL which has a space in it. I've tried this:</p>
  
  <pre><code>RewriteRule ^article/with%20spaces.html$ /article/without_spaces.html [R=301,L]
  </code></pre>
  
  <p>... but it doesn't work. Putting in a space instead of %20 causes a 500 Internal Server Error. How do I add a space?</p>
