2. 2 Rule thứ hai: Eligible for cache + Edge TTL (ví dụ 1 ngày hoặc 1 tuần) cho /assets/*. Second rule: Eligible for cache + Edge TTL (e.g. 1 day or 1 week) for /assets/*. Rule ទីពីរ: Eligible for cache + Edge TTL (e.g. 1 day or 1 week) សម្រាប់ /assets/*។

   Nhập: Enter: បញ្ចូល៖ URI Path starts with /assets/ → Edge TTL: 1 day (override origin nếu origin gửi no-cache nhầm) URI Path starts with /assets/ → Edge TTL: 1 day (override origin if origin mistakenly sends no-cache) URI Path starts with /assets/ → Edge TTL: 1 day (override origin ប្រសិនបើ origin ផ្ញើ no-cache ខុស)

3. 3 Đặt rule cụ thể trên rule rộng. Purge sau mỗi release frontend. Put specific rules above broad ones. Purge after each frontend release. ដាក់ rule ជាក់លាក់ខាងលើ rule ទូលំទូលាយ។ Purge បន្ទាប់ពី frontend release នីមួយៗ។

Cẩn thận Watch out ប្រុងប្រយ័ត្ន

• Purge Everything trên site lớn — stampede về origin. Ưu tiên purge URL hoặc prefix. Purge Everything on a large site stampedes the origin. Prefer URL or prefix purge. Purge Everything លើ site ធំ stampede origin។ ចូលចិត្ត purge URL ឬ prefix។
• TTL dài trên HTML không có versioned asset — user kẹt bản cũ. Long TTL on unversioned HTML leaves users on a stale page. TTL វែងលើ HTML គ្មាន version រក្សាអ្នកប្រើលើទំព័រ stale។

Mẹo Tips គន្លឹះ

• Hashed filenames (app.abc123.js) cho phép TTL dài an toàn. Hashed filenames (app.abc123.js) make long TTLs safe. Filename hashed (app.abc123.js) ធ្វើឱ្យ TTL វែងមានសុវត្ថិភាព។
