Zorla yenileme, kenar d\u00fc\u011f\u00fcmlerindeki belirli \u00f6nbelle\u011fi hemen temizler ve bir sonraki kullan\u0131c\u0131 iste\u011finin orijinal kaynaktan yeni i\u00e7erik \u00e7ekmesini sa\u011flar. \u00d6n y\u00fckleme ise, g\u00fcncellenmi\u015f i\u00e7eri\u011fi aktif olarak t\u00fcm kenar d\u00fc\u011f\u00fcmlerine iletir; b\u00f6ylece kullan\u0131c\u0131lar ilk isteklerinde \u00f6nbelle\u011fi bulabilir ve en iyi deneyimi elde ederler.<\/p>\n\n
