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?

As this attribute is configurable*, it is possible to delete all the cookies by setting the “expiry” to any value that has already passed. The cookie property of the current document is used to modify the attributes of the cookies buy using HTML DOM cookie Property.
JavaScript can create, read, and delete cookies with the document.cookie property.
Note that a cookie created via HTTP with the httponly attribute cannot be deleted using the JavaScript API.
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.
