multistore url

[llegrand]

does the multistore use it's own domain name?  Since we have to direct it to the default store,  does it use the default store url

Here's what I mean,

default is  mymainstore.com
second store is  secondstore.com

What is in the url when a customer goes to secondstore.com?
What I want them to see is secondstore.com

You can use first or second level domain. This is based on your web server settings.
