Question

I am testing a web app that writes cookies to subdomain.thisdomain.com and several subfolders within that. I’m looking for JavaScript that I can put into a bookmarklet that will delete all cookies under that subdomain, regardless of the folder in which they exist.

Any ideas?

Answer 1

Derived from my answer here:

javascript:new function(){var c=document.cookie.split(';');for(var i=0;i<c.length;i++){var e=c[i].indexOf('=');var n=e>-1?c[i].substr(0,e):c[i];document.cookie=n+'=;expires=Thu, 01 Jan 1970 00:00:00 GMT';}}(); return void(0); 

Due to browser security issues, this will only work when executed while on a page that has access to all the cookies you want to delete.
