I am deploying an application to several sub domains and need to set a  
global variable in each sub domain so that I query the correct table  
based on the sub domain. Currently I am doing this in my layouts but  
this doesn’t seem like a good practice.

Does anyone know of a way to set this global variable when I deploy  
using capistrano?
