使用路由和重定向来防止相同内容上的重复链接

Imagine we have the controller

class Test 
{
   public function index()
   {
     echo 'hello!';
   }
} 

So I can call it like test/index or for the best practice set route something like $routing['test'] = 'test/index';

So now I can call it with two ways test or test/index and same page have two links! So I want to know what would be the best solution for this situation?

All that I am thinking maybe check in index if I have in segment 'index' so redirect to route just 'test'.

I working with Codeigniter but I think this is question is SEO'specific too.

Summary: What would be the best to prevent double linking for the same content if I use routing?

Thanks!

Wall called .htaccess rule stopped you. Try this way:

#instead of test put name of your default controller
RewriteRule ^(test(/index)?|index(\.php)?)/?$ / [L,R=301]
RewriteRule ^(.*)/index/?$ $1 [L,R=301]

I found this great piece of code on this page where you can see basic but extensive .htaccess file for use in CI made websites / applications.
