No, cross domain restrictions would still apply although if the page were a trusted site and security restrictions were reduced it may work. For this you'd really have to be in an intranet situation.
It would be a severe security risk if web pages could do this. They could load bank logon pages into a secondary frame and read the cookies from the bank site as well as other personal info.
You will have to use some sort of server side proxy.
