Origin Shield

Enable the origin shield by setting the Use origin shield setting to active. With origin shield enabled, only the shield server will contact your source server (origin) to generate its CDN cache. Other CDN servers will contact the shield server to build their own cache. This reduces the origin load.

Origin

The Origin (or the Source Server) - Your physical or virtual HTTP(S)-accessible server hosting the source directory with files you intend to distribute via the CDN, primarily designed to handle incoming requests. For example, the origin may host your website’s source code or content folders. Anycast CDN uses the source server to cache the original files and proxy requests for non-cached files.

There are two origin shield options available for you to choose from:

Auto (Origin-based)

The auto option means that the CDN will utilize the server closest to your origin server as the shield server.

Custom (Multi-shield)

The custom option allows the CDN to use different shield servers for different geographic locations. When enabled, the location of available shield servers will be displayed in the user panel.

This will reduce the number of direct requests to the origin and ease the load on your source servers. The default origin shield location is determined automatically.

To select the preferred shield-server location manually, activate the origin shield, select the Custom option as shown above, and activate the more geographically appropriate shield from those offered.
