title: how to make this URL case insensitive
body: <p>Following is the content of my <code>.htaccess</code> file:</p>
  
  <pre><code>&lt;IfModule mod_speling.c&gt;
  CheckSpelling On
  CheckCaseOnly On
  &lt;/IfModule&gt;
  # BEGIN WordPress
  &lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /blog/
  RewriteRule ^index\.php$ - [L,NC]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /blog/index.php [L,NC]
  &lt;/IfModule&gt;
  
  # END WordPress
  </code></pre>
  
  <blockquote>
    <p>Note: <strong>blog</strong> directory exist on server</p>
  </blockquote>
  
  <p>I like to write a RewriteRule or any other thing, which can change or rewrite this <code>www.example.com/BLOG/anything-here/foo/bar</code> to <code>www.example.com/blog/anything-here/foo/bar</code></p>
  
  <p>in other words all i want is to change the case of word <strong>BLOG</strong> into lowercase <strong>blog</strong></p>
  
  <p>i tried to use <code>CheckCaseOnly On</code> but its not working, although its working for other words in the url, but its not working for this specific <strong>blog</strong> word, which is the rewritebase </p>
