我有這個單頁面應用程序，當用戶被成功驗證並重定向到儀表板時，會發出7個Ajax的http請求。當用戶登錄passport進行身份驗證並創建會話時，會重定向到儀表板。當儀表板加載它時，會使7 ajax調用服務器以獲取用戶數據。在本地主機上，它工作正常，但是當此應用程序部署在遠程雲服務器，如果我訪問使用Android設備如智能平板或Windows 10的網站它仍然按預期工作，但在成功驗證和重定向到儀表板後，Windows 7和8，那些假設獲取用戶數據的ajax調用不起作用。當我在遠程服務器上安裝req.user時，它說在該端點內未定義。看起來會話未被設置或被破壞。快速會話在localhost，android設備，windows 10和windows 7或8上的工作方式不同
