I am in the process of trying to resolve this problem and to try and increase my SEO "brownie points".
1. I used to have "...com/joke/view/123/
2. changed to this "...com/joke/show/123/
3. then changed to "...com/joke/show/this_is_a_funny_joke/123
4. later changed to ...com/joke/_of_the_day/this_is_a_funny_joke/123

Items 1,2 and 3 are now redirected to '/joke/of_the_day/'

My controller code:

Code:

//=============================================
//
//  ensure parameters are in the correct order
//
//=============================================
function of_the_day($joke_title='Joke_of_the_day', $joke_idx = 123456)
{
  // ensure at least one parameter is numeric
  // make into the correct order
  if (is_numeric($joke_title))
  {
    $joke_idx = $joke_title;
    $data     = $this->m_lib->m_getjoke(NULL, $joke_idx);
        
    $joke_title    = url_title($data['joke_title'], '_');
        
    // now put in the correct order and permanently redirect
    redirect('/joke/of_the_day/' .$joke_title .'/' .$joke_idx, 'location', 301);
    exit;
  }else{
    $data = $this->m_lib->m_getjoke(NULL, $joke_idx);
    /* // results
      [joketitle]  => Joke of the day
      [joke_title] => Did you know
      [joke_id]    => 946        
      [joke_memo]  => Michael Jordan having "retired," with $40 million ...  
    */
  }    
  // remove trailing slash to make consistent with Googles "Duplicate meta descriptions"
  $data['joke_id']    = str_replace ('/', '', $data['joke_id']);
            
  $this->j_view($data);
}//endfunc
