Question
How to set a friendly url for my module page, actually I need just to remove a module
from my url: http://mystore.com/module/mymodule
and it's must to be just http://mystore.com/mymodule
?
[
1. upd ]
I think it would be not right if I get rid of a module
in a preferences and set {module}{/:controller}
instead of module/{module}{/:controller}
So I need this url only for my module, not for all.
