Yes, because cookies (i.e. the forms authentication ticket, session id, etc) are stored once for a single web site. Typically, if you open a new window from an existing browser window the two windows share the same session data. Now in I.E. I know that you can start a new process (don't use File->New Window but rather start it again from the program icon). This new process will not share session cookies. However, any cookie that is persisted with an explicit expiration will be shared.
