Show iframe with Cookie Support?

I’m working on a plugin to import highlights from Amazon kindle’s cloud reader. I’m trying to load the page so that I can scrape it, but the user needs to log in for that to happen.

Unfortunately the user can’t login without cookies enabled and I can’t get the iframe that I’m using to enable cookies.

Any ideas?

Hi

Just to complement, this would be useful for me too, the embeds never work on sites requiring logins.
