1. You setup DNS A records (typically) for the additional URLs, pointed to the site IP addresse(s), in your domain management
2. When a request comes into IIS for a URL, it associates it to the site and hands the request over to the software
3. The software attempts to identify the request based on the URLs entered in the Domains tab per store ID
4. If the software finds a match, it displays the appropriate skin and settings for that store ID. If it does not find a match, it displays the default store in the domains tab.

Create the store in IIS

1. First, create the additional store you’re going to be using in IIS. This can be done several ways. While the example below shows separate websites for each store, the storefronts can all be applications under one website, separate sites, or even just domain aliases of the first site you set up. The important thing to note here is: each site/application should use the same home directory – wherever you installed the software. They all run off of the same copy of the files and the same database.
   
   This step may be skipped depending on the site host. Please check with your site host concerning proper IIS setup as needed.
   
   If you only have a single IP to use for testing sites, you can ‘fake’ additional websites by modifying the host file. See this page for directions on how to do that.
   
   
   
   
   Additional Considerations: The MultiStore installation should only use a single application pool for all the "stores". Using separate AppPools is not the best way to do this, especially for a large amount of stores, since it will create a new worker process for each store. That means that the same code is loaded into memory multiple times for each store, rather than just loading the code once, regardless of which store is currently being accessed.
   
   We recommend setting up a single website in IIS with a single application pool to use for all the stores. The stores should all share the same IP address and be secured with a MultiDomain (UCC or wildcard) SSL certificate to cover all the store domains.
   
   

1. In the admin console, navigate to Configuration > Manage Stores.
   
   
2. Click Create Store. Enter a name for the store in the Store Name field. Enter the store URLs in the Production, Staging, and Development fields, then select which Skin ID to use for the MoreStore. Click Save.
    
   
   
   
3. Click the Refresh Store button in the upper right of the admin console.
   
   
4. Follow the directions here to license the MoreStore.
