Feature Overview

Before start using eSurfing Cloud CDN you need to add your custom origin servers here. You can configure one or more origin servers by specifying IP addresses or hostnames (used for DNS resolution to get origin IP addresses). If multiple origin servers are configured, you can set the priority level and weight for each origin server for load balance.

Scenario	Feature Description	Configuration Method
Multiple-level primary and backup origin servers with weight	You can configure multiple primary and backup origin servers with different weight.	Go to CDN console > Domain Management > Domain List > Back-to-origin > Origin Servers.
Consistent hashing	You can apply consistent hashing based on URLs to multiple origin servers at the same level. This can ensure that different requests of one particular URL always go back to the same origin server.
