title: Password reset code example request on parsing url
body: <p>I'm developing with Codeigniter and working on password reset using a similar model to Amazon: The user clicks on a link that I email and this leads into the controller that launches the appropriate view. However I need to attach some tokens to the end of the uri for security reasons. Where do I intercept the uri within Codeigniter so as to remove the tokens? I would appreciate a code snippet that demonstrates this.
  Many thanks in advance.</p>
