Huawei Cloud CDN Will Adjust the Cache Logic of Status Code 400

Huawei Cloud CDN will adjust the default cache logic of status code 400 from a 3-second time to live (TTL) to no cache at 00:00 on June 7, 2024 (Beijing time). After the new logic goes online:

1. If you have never modified the cache logic of status code 400 for a domain name, the new cache logic is used and status code 400 is not cached.
2. If you have modified the cache logic of status code 400 for a domain name, the cache TTL you set is used. For example, if you have set the cache TTL of status code 400 to 10s, after the new cache logic goes online, the cache TTL is still 10s.
3. For details about how to modify the cache TTL of status codes, see Status Code Cache TTL.
