If you answer this and actually know what you're talking about, I'll +rep you for helping me out. After all, that's the whole point of rep, right? Please don't bother if you're just guessing. 1. Do iframes pass on cookies? (saw a post about this and thought I'd ask) 2. What does the site in the iframe show as the referrer? The site url the iframe is placed on, a blank referrer, framed.php, or something else? 3. Is there anyway the site in the iframe can tell its being iframed (i.e. only portion of page is being viewed) if you take care of the referrer issue? If there is, would scroll bars take care of this? (seen iframes with scroll so you could scroll and view every part of the page, just not everything at once) Thanks!
