title: Case Insensitive Routing in CodeIgniter
body: <p>I've written this in the CodeIgniter's routers.</p>
  
  <pre><code>$route['companyname'] = "/profile/1";
  </code></pre>
  
  <p>This is working fine but when I type "CompanyName" into the URL then it doesn't work. This is because upper case characters. </p>
  
  <p>I want to make this routing case insensitive. Please suggest the best way.</p>
