clear cache

[dreamwest]

So i have a page cached with php pragma headers. How can i clear the cache when someone sets a cookie:

 

<script>
function set_cookie(object, value) { 
var expireDate  = new Date()
var expstring   = expireDate.setDate(expireDate.getDate() + 500)
document.cookie = object+'='+value+'; expires='+expireDate.toGMTString()+'; path=/';

window.location.reload()  
}
</script>

<a  onclick="set_cookie('list', '1');"  href="javascript:void('0');">Set cookie and clear cache</a>

You can simply generate a random number and add it to url query, for example

 

window.location =  my_url.php?random_number=1234455666
