// You can use this set of IF/ELSE statments to check and use a basic cookie value. 

if(document.location.pathname === "/") { // CHECK THE PAGE

    if( $.cookie('homepage-redirect' ) !== '1') { // CHECK FOR EXISTING COOKIE

         $.cookie('homepage-redirect', 1); // SET THE COOKIE IF IT DIDN'T EXIST
         document.location="/other.html"; // THEN REDIRECT TO OTHER PAGE

    } else {
        // DO NOTHING IF COOKIE IS SET
    }
