title: Disable url correction / rewriting by codeigniter for SEO
body: <p>I have CI 1.6 installed, with basic url library and usual config/routes.php file.
  But in my case all of the following urls works:  </p>
  
  <pre><code>mysite.com/products/id/919330  
  mysite.com/products/id/919330/  
  mysite.com//products/id/919330 - (see double slash!)  
  mysite.com/products///id/919330/ - (even this!)
  </code></pre>
  
  <p>As my SEO-guy says that i need to redirect them all to the first variant<br>
  <strong>mysite.com/products/id/919330</strong> or to give 404 by all except the first one.  </p>
  
  <p>Where i could try to make corrections to disable this clever URL detecting by CI?</p>
