After fixing famous bug in CookieContainer about leading dot in hostname (FeedbackID=478521, also described in http://dot-net-expertise.blogspot.ru/2009/10/cookiecontainer-domain-handling-bug-fix.html), there is a new bug, that came to replace old one.

Now, when you're setting RFC2109-cookie (Version=1) for parent domain ".site.com", you cannot get it back for subdomain "www.site.com".

See attached project for more tests reproducing the problem.

Workaround #1: after receiving response with Version=1 cookies, add them to new CookieContainer as plain cookies, and then use this new container to make subsequent requests.

Workaround #2: after receiving response with Version=1 cookies for parent domain, add them to same CookieContainer once again, now for subdomain.

All these workarounds are very inconvenient when request is automatically redirected, so you cannot insert this additional cookie processing between original request and redirected one.
