Disable a link possible?

Hi,

I want to disable a link and route. Is it possible? i.e

PHP Code:

$route['test/admin'] = 'admin'; 


myproject.com/test/admin now going to myproject.com/admin, this is ok. But still myproject.com/admin link is working.


What i have need that disable the link so that no one can access through this link myproject.com/admin

I love my work
