कैश का प्रबंधन कैसे और कैसे करें)
ऐसे कई उपकरण हैं जो वेब डिजाइनर और वेबमास्टर ठीक-ठीक उपयोग कर सकते हैं कि कैश उनकी साइटों के साथ कैसे काम करेगा। इससे आपको सर्वर कॉन्फ़िगरेशन के साथ थोड़ा परिचित होना पड़ सकता है, लेकिन यह इसके लायक है। अपने सर्वर के साथ काम करने के लिए इन उपकरणों का उपयोग करने के तरीके के बारे में अधिक विस्तृत जानकारी के लिए, नीचे दिए गए "
कार्यान्वयन " अनुभागों (अनुवादक के नोट - अगले भाग में) को देखें।
