I want to use Radiant to host multiple sites. I’ve read the article on how to configure the directory structure, etc. My question pertains to how it actually works. I looked at the database, and I don’t see anything that designates which site pages or their snippets belong to. If I have [mysite1.com](http://mysite1.com) and [mysite2.com](http://mysite2.com) both residing under the same installation, how does radiant know which page in the database is the default page for [mysite1.com](http://mysite1.com) and which page is the default page for [mysite2.com](http://mysite2.com) ? I didn’t see anything in that article that even referred to database configuration modifications. So any help you can provide to a rails newbie is appreciated. Cheers, Travis ---

The way the virtual domain extension works is to read the hostname from the incoming request, then use that to decide which immediate child of the root page should be accessed. The root page of the Radiant installation is given a “Virtual Page” type and a “config” part (tab) that contains the configuration. Sean
