Secure domain1 form --> secure domain2 page (as an iframe)?
Will this work?

Verbose: we have a client with a https:// server. We have only http://. From my server I want to serve a form. The https:// company would then display this form via an iframe on their page. The iframe will post to my server.

I realize there's a huge security problem, so I've gotten an OK from my company to buy a secure certificate to make it secure --> secure.

Question: even if they're both secure, I'm worried that my $800 spent on a certificate will be wasted because I have a feeling this will still be regarded as a security risk to browsers, namely IE6. Your thoughts?

Sorry this is not entirely within the world of ASP. Trying to ping those that have secure domain experience.
