Redirecting one zen cart to another during payment

I want to accept payment with google. I have an ssl certificate for one web address but my zen cart is on another. I do not want to have to purchase another ssl certificate but I need to be ssl certified to accept google, as most of you probably know.

So, I need to know how to redirect my zen cart to the other web address during payment. How do I do it so that the shopping cart and accounts work out.

For example, I want them to say on site 1 during looking at items and putting them in cart and making their account. During payment, I want it to at some point change sites to site 2 that has ssl so that google will work with it.

How do I do that?

This is not proper. Buy an SSL cert, you dont need to buy the expensive ones. Buy one of the cheap rapidssl or something similar.

But is it possible to do this type of redirect?

No .
