title: index.php to root in htaccess
body: <p>What does this mean? I am trying to remove index.php from the URL and point to root. For example,
  <a href="https://www.example.com/index.php" rel="nofollow noreferrer">https://www.example.com/index.php</a> redirect to <a href="https://www.example.com/" rel="nofollow noreferrer">https://www.example.com/</a> 
  The below solution works absolutely fine. However, I am unclear about the HTTP/ used in RewriteCond line. What does it do? Can someone please explain?</p>
  
  <pre><code>RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ HTTP/
  RewriteRule ^index\.php$ https://www.aviatrix.com/$1 [R=301,L]
  </code></pre>
