爲什麼我每次都必須重新啓動rails才能在這裏測試404.html頁面？

我想解決爲什麼當我在工作的一個rails應用上工作時，要查看我對頁面上的html所做的更改的唯一方法是使用ctrl-C然後致電script/server。爲什麼我每次都必須重新啓動rails才能在這裏測試404.html頁面？

至於我可以告訴大家，我也看不出什麼特別的毛病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"

這本身並不能在本地顯示錯誤頁面，所以在application_controller.rb我已經別名rescue_action_locally到rescue_action_in_public方法，阻止我看到堆棧跟蹤：

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

在這裏，這說明我的錯誤頁面一次，但隨後緩存，這樣，以後重裝顯示HTML文件時，本身的狀態rver被加載。

日誌輸出不告訴我任何奇怪的緩存行爲 - 它得到的請求不存在的資源，沒有找到任何東西，然後在渲染HTML頁面的要求：

[email protected] ~/RailsApps/annoying_app > script/server --debugger 
    => Booting Mongrel 
    => Rails 2.3.2 application starting on http://0.0.0.0:3000 
    => Debugger enabled 
    => Call with -d to detach 
    => Ctrl-C to shutdown server 
    SQL (0.2ms) SET SQL_AUTO_IS_NULL=0 

    Processing ApplicationController#index (for 127.0.0.1 at 2009-12-28 19:23:27) [GET] 

    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完全是靜態的，根本沒有任何ERB，這個靜態html頁面是頁面刷新之間不會改變的。

我在這裏做錯了什麼？這真讓我抓狂！
