What is the cookie size limitation for IE9 and IE 10?

I know that for IE 8 following RFC 2109 it is 4kb. Is it the same for IE 9 and IE 10?

    According to this site (http://browsercookielimits.iain.guru/) (mirror here) IE8, 9 and 10 behave in the very same way.

    In the doubt that this may be outdated, I ran the test with my version of IE (10.0.9200.16580) and got pretty consistent results:
