我在本地爲我的開發環境運行Webricks/Thin服務器,但是我無法在我的響應中返回Etag。如何在使用WEBRICK/Thin的rails 3.2.12中使用開發模式啓用Etag我使用WEBRICK/Thin的
我已經嘗試過所有關於添加Etag或ConditionalGet機架中間件組件的選項,但無濟於事。這裏是我的development.rb文件
config.middleware.use Rack::Cors do
allow do
origins 'xyz:3000', 'abc:3000'
resource '*', :headers => :any, :methods => [:get, :post, :options]
end
config.middleware.insert_before(Rack::Cors, Rack::ConditionalGet)
config.consider_all_requests_local = true
config.action_controller.perform_caching = true
在這裏,段來自請求樣本響應報頭和那失蹤的eTag頁眉或HTTP_IF_NONE_MATCH和HTTP_IF_MODIFIED_SINCE頭,因此所有的請求返回200 OK,從來沒有在304未修改其中
> curl --head -I mylocalhosturl
HTTP/1.1 200 OK

有趣的是,這不是生產中使用類似配置AFAIK但nginx/1.2.0作爲服務器的問題。任何關於在Rail開發模式中啓用Etags的想法都會很讚賞。
太好了,幫了很多,謝謝。 – veritas1
非常感謝。你剛纔救了我幾個小時。 – Tintin81
或根據您的'production.rb'中的'Rack :: MiniProfiler.config.disable_caching = false'這樣的官方文檔禁用該行爲 https://github.com/MiniProfiler/rack-mini-profiler#caching-行爲 – MhdSyrwan
