title: Redirection to custom 404 error page
body: <p>I was not able to find a straight answer for my question. I have 2 other websites (eg website 'A' and website 'B') under my current website (www.xyz.com). Both the website is in different folder. So to access my sub website url will be www.xyz.com/A/ or www.xyz.com/B/. I have created a 404.html page for my main website (www.xyz.com). How can I use the same 404.html page for my sub websites. I tried <code>ErrorDocument 404 /404.html</code></p>
  
  <p>It is working for my main website, but not working for my sub websites kindly advice.</p>
