Methinks you missed the point - though I wouldn't condone this practice, :-)
- point your iframe at server side SCRIPT instead of third party site (and devise some way to tell it "which site")
- Server side script CURLS third party site
- third party site is now the output of server side SCRIPT which is now **on your server,** not on third party site
- You can modify the contents of this frame because the content comes from your server.
