Why access enterprise, operation and maintenance first let the request go through CDN
1 CDN can cache resources, some static resources are not configured to use qbCDN, go to CDN, CDN will cache these resources
2 Using CDN, CDN can provide a faster access link to the back-end server, which is faster than allowing users to directly access the public IP of the enterprise
VS puts static resources directly on the CDN. It is a safer way to send static resources directly to the CDN, because the application does not need to go to the CDN.
