Im just confused how to build this URL (easy question for you guys, I think)

[eluser]towki[/eluser]
Please see this image, I cannot attach files

My method/function "administration" in my "Infosystem" controller loads a view that serves as an administration page that is only accessible by admins.

For example an admin logged in typed "www.example.com/infosystem/administration" my administration page will be showed up consisting of several administrative functions.

Speaking of this administrative function, My problem exactly is I want to have a link on this administration page that point to another view/page that function as managing the users,
and that link should have a URL like this "www.example.com/infosystem/administration/user_management".

If not for my URL concern, I could have created my user_management page by creating another function in my controller and loading a view. but i think that will not create the URL that I want.

Just a newbie. Please help me with this
