The cookie specs require two names and a dot between, so your cookiedomain cannot be "localhost". Here's how I solved it:

2. When developing you use http://dev.livesite.com instead of http://localhost

3. Use ".livesite.com" as cookiedomain (with a dot in the beginning) when creating the cookie. Modern browsers doesn't require a leading dot anymore, but you may want to use anyway for backwards compability.

4. Now it works on all sites:

   • http://dev.livesite.com
   • http://www.livesite.com
   • http://livesite.com
