Merhaba<\/p>\n

Bu i\u00e7eri\u011fimizde, hem istemci hemde sunucu taraf\u0131nda \u00f6nbelle\u011fe alma sorumlulu\u011funu g\u00fcden Response Caching middleware’ini inceleyece\u011fiz. <\/p>\n

Response Caching ile \u00f6nbelle\u011fe al\u0131nm\u0131\u015f olan endpointler yap\u0131lan ilk request neticesinden sonraki t\u00fcm requestlerde belirtilen s\u00fcre \u00e7er\u00e7evesinde \u00f6nbellekten cevapland\u0131r\u0131lacakt\u0131r. Dolay\u0131s\u0131yla ilgili endpointler yersiz istekler ile l\u00fczumsuz yere me\u015fgul edilmeyecek b\u00f6ylece uygulama sunucusu gereken i\u015flemlere daha \u00e7ok odaklanabilecek ve total maliyet minimize edilmi\u015f olacakt\u0131r.<\/p>\n

Response Caching middleware’ini uygulamada kullanabilmek i\u00e7in ilk olarak ilgili projeye “Startup.cs” dosyas\u0131ndaki “ConfigureServices” metodu i\u00e7erisinde “AddResponseCaching” fonksiyonuyla a\u015fa\u011f\u0131daki gibi servis olarak dahil edilmesi gerekmektedir.<\/p>\n

\r\n        public void ConfigureServices(IServiceCollection services)\r\n        {\r\n            services.AddResponseCaching();\r\n        }\r\n<\/pre>\nResponse Caching tan\u0131mlamas\u0131n\u0131 yaparken a\u015fa\u011f\u0131daki \u00fc\u00e7 parametreyle ayarlar\u0131na m\u00fcdahalede bulunabiliriz.<\/p>\n
\nMaximumBodySize<\/strong> : Response Body’ler i\u00e7in ge\u00e7erli maksimum boyut. Varsay\u0131lan olarak 64 MB’t\u0131r.<\/li>\n

\nDuration<\/strong> : Response’un saniye cinsinden ne kadar s\u00fcre cache’de tutulaca\u011f\u0131n\u0131 belirtti\u011fimiz \u00f6zelliktir.<\/li>\n
