Use the “return” statement to fix this issue.

(E.g)

def do_something
redirect_to(:action => “elsewhere”) and return if monkeys.nil?
render :action => “overthere” # won’t be called if monkeys is nil
end

Make sure you have; “mongrel_cluster” gem installed.

You can see whether it exists in the list by issuing the command;

gem list –local

If you don’t see it, run;

gem install mongrel_cluster

That should fix your issue.

Edit your environment configuration and add something like this;

(E.g in environment.rb or production.rb)

config.action_controller.session = {:domain => “.arthurneil.com”, :key => ‘_arthurs_session_id’, :secret => ‘4gfsdf234jmfv35ksdf23m44m4m4neserf345′}

(E.g)

cookies[:my_test_cookie] = {:value => “test”, :expires => 365.days.from_now,:domain => ‘.arthurneil.com’}
