title: using .htaccess to append .html behind url path
body: <p>People are coming into my website like this:</p>
  
  <p><code>sitename.com/brands/brandA</code></p>
  
  <p>But this will cause an 404 error because I actually need them to come to this url</p>
  
  <p><code>sitename.com/brands/brandA.html</code></p>
  
  <p>How can I append the .html extension automatically when needed when someone enters <code>sitename.com/brands/*</code> with no .html extension using the <code>.htaccess</code> document.</p>
