My current URL is: www.example.com/category/we-developer/ However, if any user mistakenly adds extra characters after the /, for example, www.example.com/category/we-developer/fgggfgg, it should take him to a 404 page. But instead, the user is again viewing the previous page (www.example.com/category/we-developer/)This is why Google is showing it as a duplicate page. What I wish is that instead of opening the same page, the user would be taken to a '404` page.Can you advise on how to do this? Note that my site is using CodeIgniter.
Duplicate content error results instead of a 404 page
