Hello I need to destroy javascript cookies on a page refresh. I need to set a new bunch of cookies on every page load which help me render the web page based on user options. Is there a method to destroy cookies on a page refresh??
May be you could remove cookies on page unload.
For example, with jQuery:
$(window).unload(function() {
//Destroy cookies here
});
You need to detect the page refresh, have a look at:
Detecting Page Refreshes :: Using JavaScript on Client-Side
Once you know that, you should be able to delete the cookies.
