I've installed the multisite extension on SS3. It's working fine from what i can see in the CMS. I struggling to see how this actually works. Not a lot of documentation out there as to how it should work.
I have a dropdown and i can create another subsite. How do i test/view it? I would like to have 1 instance of SS with a few microsites running off the same CMS.
The Multisites module actually adds objects into the site tree that represent the website. Editors are fully aware of all the different "sites" being managed in the system, and there's never any session based tracking of which 'site' you're currently in, it works purely off the current URL.
The Subsites module will try and make it appear that the silverstripe instance is just one single site, ie in the CMS admin view, you only see content from the 'current' site. You can change which site you're viewing, but the admin view appears as though you're just managing a single site.
