title: How to make this .htaccess rule case insensitive?
body: <p>This is a rule in my .htaccess</p>
  
  <pre><code># those CSV files are under the DOCROOT ... so let's hide 'em
  &lt;FilesMatch "\.CSV$"&gt;
   Order Allow,Deny
   Deny from all
  &lt;/FilesMatch&gt;
  </code></pre>
  
  <p>I've noticed however that if there is a file with a lowercase or mixed case extension of CSV, it will be ignored by the rule and displayed.</p>
  
  <p>How do I make this case insensitive? </p>
  
  <p>I hope it doesn't come down to  <code>"\.(?:CSV|csv)$"</code> (which I'm not sure would even work, and doesn't cover all bases)</p>
  
  <p><strong>Note:</strong> The files are under the docroot, and are uploaded automatically there by a 3rd party service, so I'd prefer to implement a rule my end instead of bothering them. Had <em>I</em> set this site up though, I'd go for above the docroot.</p>
  
  <p>Thanks</p>
