The current mobile setting will be highlighted. If nothing is highlighted, then a choice has not been made on the current device.
Given a response, a cookie may be stored in the browser. Actions that cause a cookie to be stored are: "Yes. Always redirect me on this device." and "No. Never redirect me on this device."
Choosing the first "Yes. Always redirect me on this device." will cause future site visits to redirect automatically to the mobile version of the site without displaying the prompt.
Choosing the second: "No. Never redirect me on this device." will cause future pages to not display the prompt and remain in the "Full version" of the page.
Note: Because a cookie determines the selected choice, clearing cookies from the browser will cause the prompt to re-appear.
