check if cookies are enabled


check if cookies are enabled  using -'php,javascript,session-cookies'

I am working on a page that requires javascript and sessions. I already have code to warn the user if javascript is disabled. Now, I want to handle the case where cookies are disabled, as the session id is stored in cookies.

I have thought of just a couple ideas:


Embedding the session id in the links and forms
Warn the user they must enable cookies if they are disabled (would need help detecting if cookies are disabled)


What is the best way to approach this? Thanks

EDIT

Based on the articles linked, I came up with my own approach and thought I would share, somebody else might be able to use it, maybe I will get a few critiques. (Assumes your PHP session stores in a cookie named PHPSESSID)

<div id="form" style="display:none">Content goes here</div>
<noscript>Sorry, but Javascript is required</noscript>
<script type="text/javascript"><!--
if(document.cookie.indexOf('PHPSESSID')!=-1)
   document.getElementById('form').style.display='';
else
   document.write('<p>Sorry, but cookies must be enabled</p>');
--></script>
