title: Programmatically Detecting Browser Cookies Enable/Disabled without Redirect or Javascript?
body: <p>How is <a href="http://supportdetails.com" rel="nofollow noreferrer">http://supportdetails.com</a> detecting if cookies are enabled or disabled without a server side redirect?</p>
  
  <p>Using Firefox and the Developer plug I've disabled Javascript and toggled Cookies on and off. It correctly detects without, as far as I can tell, a server side redirect. How are they doing this?</p>
