This refers to a network node that CDN uses to cache the content of your origin server in order to quickly respond to user requests from different regions.
A CNAME (Canonical Name) record refers to the alias record in a domain name resolution.
For example, a server named
host.example.com provides both WWW and MAIL services. To make it easier for users to access those services, two CNAME records (
mail.example.com) can be added for this server at its DNS service provider, and all requests to access these two CNAME records will be forwarded to
This refers to a domain name suffixed with
.cdn.dnsv1.com that is assigned by the system to the connected acceleration domain name configured on the CDN Console. You need to configure a CNAME record at your domain name service provider. After the record takes effect, CDN will take care of domain name resolution, and all requests made to this domain name will be forwarded to the edge servers of CDN.

Examples include html, css and js files, images, videos, software installation packages, APK files, and compressed files.
This refers to content that varies in the responses to multiple requests for the same resource.

In CDN, an origin-pull means that when a user sends a request from a browser, the server that responds to the request is the server of the source website rather than a cache server on a CDN node. Generally, if the content is not cached on the cache server or is modified on the origin server, it will be pulled from the origin server.
This refers to the site domain name accessed on the origin server by a CDN node during origin-pull. For more information, please see Origin Server Configuration.
This refers to a set of server addresses that users can easily remember and use, and can be a website, email, FTP, etc. It is used to identify a computer’s electronic location (sometimes referred to as geographic location) during data transfer.
In COS, a bucket is for storing a object or multiple objects. A bucket name is a user-defined string connecting a system-generated numeric string with dash, thus ensuring that this bucket name is unique. For more information, see Bucket Overview.
