Using Javascript ReadCookie() Function

ReadCookie(), you realize immediately, is used to read a cookie.

You can read any cookies, provided they are being read on the same domain they were set at. 

<script type="text/javascript" language="JavaScript">
var acookie = ReadCookie("cookiename");
if(acookie.length == 0)
 { 
  //redirect somewhere 
 }
</script>

if( document.cookie.indexOf("cookiename=") < 0) {
    alert("Cookie not found, redirecting you.");
    location.href = "newpage.html";
}

Be careful not to use a cookie name that may be the end of another cookie name. If this is likely, you'll need to do a full cookie read, or use PHP instead.

if( $.cookie('cookiename') == null ) { 
    alert("OH NOES U NO HAS COOKIE");
    window.location.replace('http://url');
}
