I'm just starting to give RoR a go (RoR3 to be precise), and I'm wondering about hosting. For PHP applications, it's easy to run multiple of them on the one site (eg. in different subdirectories, subdomains, or addon domains).
It seems that for RoR hosting, it is only ever one application per "server" - so for instance you can no longer install apps in subdirectories.
Is this assumption correct? What are the different ways rails apps are hosted?
Thanks guys :-)
