Back-to-source with the same protocol

Last Updated: May 03, 2017

Introduction

When the back-to-source with the same protocol feature is enabled, back-to-source requests for resources will use the same protocol used by the client in order to request resources. If the client makes an HTTPS request for resources, but the resources are not cached on the node, a back-to-source HTTPS request will be made for resources. This protocol is also applicable for HTTP requests.

Note: The origin site must support both the port 80 and port 443; otherwise, the back-to-source may fail.

Operation procedure

  2. On the left navigation bar, click CDN domain name list.

  3. Select a domain to enter the management page.

  4. Enable or disable the Back-to-source with the Same Protocol feature.
