Help for setup CS Cart Home page


sorry for my bad english, but english is not my primary language.

Must say that is CS Cart excellent web shop software.

I must setup a company web shop with 5 subdomains

Scenario: - public webshop, visible to everybody

but partner 1-5 can't be visible to everybody, and home screen must be login form.

on my laptop i installed xampp and install CS Cart script and try to setup this but i have problem with subdomains, from scenario.

How to setup?
