Redirect checkout to another store

[Guest]

Hello;

 

It seems to me that this should be fairly simple but I don't know where to start and can't find a mod.

 

I have a ssl certificate and take credit cards. Problem is I sell wholesale as well and put it on a subdomain

 

www.wholesale.misterbling.com

 

Of course the subdomaindoesn't have an ssl certificate, if someone buys from there how do I have the cart switch over to

 

www.misterbling.com

 

for checkout?

 

They're both using a seperate database. Any ideas?
