Hi Edward,Typically, the URLs loaded within IFRAME are treated as less trustworthy.You either have to mark these sites as Trusted Sites in your browser (it will be a client side fix which works only on the specific browser in a specific client computer).Or, you need to setup something called P3P policy in your web site.Refer the URL below for more details.http://stackoverflow.com/questions/389456/cookie-blocked-not-saved-in-iframe-in-internet-explorerHope this helps.
