Need to turn off ALL caching in production environment

I’m deploying to a production environment to show a client progress on
a site, but it’s being cached strangely.

Here is my production.rb:

Settings specified here will take precedence over those in config/

environment.rb

The production environment is meant for finished, “live” apps.

Code is not reloaded between requests

config.cache_classes = true

Use a different logger for distributed setups

config.logger = SyslogLogger.new

Full error reports are disabled and caching is turned on

config.action_controller.consider_all_requests_local = false
config.action_controller.perform_caching = false
config.action_view.cache_template_loading = false

Enable serving of images, stylesheets, and javascripts from an asset

server

config.action_controller.asset_host = "http://

assets.example.com"

Disable delivery errors, bad email addresses will be ignored

config.action_mailer.raise_delivery_errors = false

What am I missing? Could mongrel be causing this?

Thanks,
Andy
