Changing the Cookie Domain Path in Rails

In rails 2.3.4+ if you want to modify your cooking information set by your system, in any of your environment files you can simple overwrite them as follows.

config.action_controller.session = {
:session_key => '_my_session_id',
:secret => '..your_secret_code_here..',
:domain => ".domain.com"

Obviously if you only want to change your domain for instance you can simple do

config.action_controller.session[:domain] = ".domain.com"
