Answer 2

+8 A:

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";}}()

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.

Is there a place to put the domain name in this JavaScript? I'd like to remove cookies within my own browser for a particular domain and all subdomains. Like "www.microsoft.com" would take anything that starts with "www.microsoft.com" and remove all cookies.

Bookmarklets play inside the browser's security sandbox, so they're not allowed to edit cookies from a different domain.

Okay. I didn't read that right. I figured anything running as a bookmarklet would have access to all browser settings.

Used the JS in a page to remove all cookies for a site. Worked great. Thx!

Answer 3

A:

Very good for create a cookieless subdomain (I mean very good to serve static resources according to Google guidelines: http://code.google.com/intl/fr/speed/page-speed/docs/caching.html)
