title: Using Htaccess Error document with absolute path
body: <p>I am using htaccess error document with absolute path instead of relative path.
  The code is</p>
  
  <pre><code>ErrorDocument 404 http://www.sitename.com/404page.html
  </code></pre>
  
  <p>Is it OK to use it like this or should it must be </p>
  
  <pre><code>ErrorDocument 404 /404page.html
  </code></pre>
  
  <p>I have some advantages in doing as absolute path ? Could you please tell me if it is OK.</p>
