title: how to display a coming soon page when a page doesn't have an index page using htaccess
body: <p>my directory looks like this:</p>
  
  <pre><code>/
  /comingsoon.php
  /.htaccess
  /domain1.com/ &lt; folder
  /domain2.com/ &lt; folder
  </code></pre>
  
  <p>i can access domain1.com on maindomain.com/domain1.com or simply domain1.com</p>
  
  <p>i want to display comingsoon.php when i get an 403 error. i tried this:</p>
  
  <p>ErrorDocument 403 /comingsoon.php</p>
  
  <p>but it only works on maindomain.com/domain1.com/ but not in domain1.com</p>
  
  <p>and i don't want to put comingsoon.php inside domain1.com, i just want it in the root, coz i have a lot of accounts</p>
