get query string, server godaddy

[eluser]Unknown[/eluser]
I want to fetch $_GET variables from http://domain.com/page1/?id=1
On my localhost, I configure uri_protocol = PATH_INFO and it works.
But on server Godaddy, to make CodeIgniter work I have to configure uri_protocol = QUERY_STRING.
But with it, I can't fetch variables from http://domain.com/page1/?id=1
How do I have to do?
