</div>

my environment.rb contains  
ENV[‘RAILS\_ENV’] ||= ‘production’

when i start webrick with command  
ruby script\server

it still runs in development mode. Is this expected behavior of  
webrick?? why?

the only way to run webrick in peoduction mode,it seems, is by :-  
ruby script\server -e production

The ||= operator indicates that if RAILS\_ENV isn’t already set, then  
Ruby should set it (in this case, to ‘production’). I’m willing to  
bet that WEBrick sets it to development before it gets to that line  
environment.rb. Try changing ||= to = (I don’t know if that will  
work).

thanks for reply, it was thoughtful

But alas,

ENV[‘RAILS\_ENV’] = ‘production’

doesn’t work either.

I think I’ll stick to -e production
