Right route, but URI has extra chars

[Nikita_kharkov]

Hello! Have such URL:

http://somehost.com/41-some-product

If I write something in products it will be ok, but it's a wrong behavior! URLs like

http://somehost.com/41-someAbrakadabra-product

still ok while I do not change id or remove dash which after id.  So can I fix it?

 

More simply: When I have request_uri /41-someAbrakadabra-product I still have access to this page - but its wrong behaviour! I want or redirect or 404. So I need accessing to this page only by right way: /41-some-product 

 

I use nginx, so, please if you have some decision make it to nginx please. Thanks
