Hi,

I’ve got a Rails app deployed at [www.main-domain.com](http://www.main-domain.com). I need to deploy  
copies of that app to subdomains like [sub1.main-domain.com](http://sub1.main-domain.com),  
[sub2.main-domain.com](http://sub2.main-domain.com), etc. Each subdomain could use the same app code,  
but each _must_ have it’s own database. (They also need their own  
images, stylesheets, etc.) None of the examples I’ve been able to  
Google up have that characteristic. They all assume a shared database  
with the subdomain’s data being filtered in the model. I would really  
appreciate any thoughts / experience / pointers to stuff I’ve missed in  
my Googling that might put me on the right track re: how to deploy this.

Thanks,  
Bill
