Answer 1

You don't need to wait while window is loaded:

<script type="text/javascript">
    var thecookie = readCookie('doRedirect');
    if(!thecookie) {
       createCookie('doRedirect','true','1');
       window.location = '/coming-soon.html';
    };
    function createCookie(name,value,days){
      // do work
    }
    function readCookie(name){
      // do work
    }
</script>

Also Petr B. said right thing: server-side redirect is better in your case.

Try this How to Run a jQuery or JavaScript Before Page Start to Load.

Btw. if you want redirect without displaying page you must use php with cookies check.
