Thanks for sharing amazing information keep posting. Thanks for the nice blog.
The multi site documentation is not very clear about how to set up additional sites and where the code is stored. You can find the multi-site code and documentation at www.salesforce.com/code/products/multi-site.
The example sentences provided are all sub-domains. For people starting out, it should have more examples and reasons.
I.e. if you have a specific brand store running alongside your main site but using the same inventory how would this be setup?
I raise this as the only partially consistent information out there at the moment relates specifically to hosting providers and each one has a different approach to the same task.
