Multishop 2 or more domains sharing customers

[armboa]

Hello

I've make several research but i don't find a clear answer to the following question:

 

Is possible to have 2 shop's sharing custommers (same group)

• With 2 domains (like www.shopA.com and shopB.com)
• The user doesn't see the connection between the 2 (so redirect is out of question)
• Without prejudice on search engines

Also when I use a subfolder to create the URL it gives me the following error

 

Ocorreu um erro ao criar um objeto. shop_url (Duplicate entry 'www.shopA.com-' for key 'shop_url')

 

 

I have a shop with the URL www.shopA.com

 

and if i fill the Phisical URL instead the Virtual URL that error appears
