Query Strings are a total turn off to CodeIgniter

I believe you're getting a 404 because if there is anything after the controller name in the query string (in your case, the thing after is "variable") it assumes it's a function of that controller. So it's looking for a function named variable and freaking out because there's not one.

Read the URL section of the user guide for more info: http://ellislab.com/codeigniter/user-gui.../urls.html

Try linking to http://domain.com/page/index/variable instead, and change your uri call from "segment(2)" to "segment(3)". That should do it.
