为什么我每次都必须重新启动rails才能在这里测试404.html页面？

我想解决为什么当我在工作的一个rails应用上工作时，要查看我对页面上的html所做的更改的唯一方法是使用ctrl-C然后致电script/server。为什么我每次都必须重新启动rails才能在这里测试404.html页面？

至于我可以告诉大家，我也看不出什么特别的毛病development.rb配置文件的位置：

# Settings specified here will take precedence over those in config/environment.rb 

# In the development environment your application's code is reloaded on 
# every request. This slows down response time but is perfect for development 
# since you don't have to restart the webserver when you make code changes. 
config.cache_classes = false 

# Log error messages when you accidentally call methods on nil. 
config.whiny_nils = true 

# Show full error reports and disable caching 
config.action_controller.consider_all_requests_local = true 
config.action_view.debug_rjs       = true 
config.action_controller.perform_caching    = false 

# Don't care if the mailer can't send 
config.action_mailer.raise_delivery_errors = false 
config.action_mailer.perform_deliveries = false 

# add rack bug 
# config.middleware.use "Rack::Bug" 

# this disables the caching for comatose, not the rest of the app 
# config.disable_caching = true 

config.action_mailer.default_url_options = { :host => "localhost:3000" } 

config.gem "thoughtbot-factory_girl", 
      :lib => "factory_girl", 
      :source => "http://gems.github.com"

这本身并不能在本地显示错误页面，所以在application_controller.rb我已经别名rescue_action_locally到rescue_action_in_public方法，阻止我看到堆栈跟踪：

# this method allows you to test 404 and 500 pages locally 
alias_method :rescue_action_locally, :rescue_action_in_public

在这里，这说明我的错误页面一次，但随后缓存，这样，以后重装显示HTML文件时，本身的状态rver被加载。

日志输出不告诉我任何奇怪的缓存行为 - 它得到的请求不存在的资源，没有找到任何东西，然后在渲染HTML页面的要求：

    ActionController::RoutingError (No route matches "/non-existent-resource" with {:method=>:get}): 

    Rendering /Users/chrisadams/RailsApps/annoying_app/public/404.html (404 Not Found)

404。 html完全是静态的，根本没有任何ERB，这个静态html页面是页面刷新之间不会改变的。

我在这里做错了什么？这真让我抓狂！
