Hi Lance,

I think I follow what you are trying to do and no it won't work. :-]

If you open an HTTPS page on Domain1 - your browser has negotiated
encryption keys exclusively for just that site (based on the domain name).
So, if you Post your form to an HTTPS page on Domain2 (a different domain
name), then your browser won't have 'keys' for Domain2 and so the form data
is sent un-encrypted.

Remember, encryption keys for a particular domain can't be obtained until
the first time you open an HTTPS page for that domain - only after being on
an HTTPS page can you then send encrypted data back to that domain.

Hope this helps a little. Cheers...
