title: Codeigniter Route ID
body: <p>I've built a webpage that, in its products page has this prototype for its url</p>
  
  <p><a href="http://www.example.com/products/show/some-really-nice-product/512" rel="nofollow">http://www.example.com/products/show/some-really-nice-product/512</a></p>
  
  <p>The last bit of the url is the product id, which serves the sole purpose of searching the db for the product.</p>
  
  <p>But, is it possible, using routing, to be able to hide that part and still be possible to search the product by its id? </p>
  
  <p>Like 
  <a href="http://www.example.com/products/show/some-really-nice-product/" rel="nofollow">http://www.example.com/products/show/some-really-nice-product/</a> ??</p>
  
  <p>Thank you</p>
