kb917072 on Http.sys cookie problem

quick question on the recent KB article "An ASP.NET page is stored in
the HTTP.sys kernel cache in IIS 6.0 when the ASP.NET page generates an
HTTP header that contains a Set-Cookie response"
(http://support.microsoft.com/kb/917072)

Does this affect Forms Authentication Cookies?
