If a client requests content that is not cached on Alibaba Cloud Content Delivery Network (CDN) nodes, the CDN nodes retrieve the requested content from the origin server. You can set a timeout period for back-to-origin requests. The timeout period specifies the amount of time that a CDN node waits for a response after a request is redirected to the origin server. The default timeout period is 30 seconds. If the CDN node does not receive a response within the specified timeout period, the CDN node disconnects from the origin server. This topic describes how to set a timeout period for back-to-origin requests.

Procedure

  1. Log on to the Alibaba Cloud CDN console.
  2. In the left-side navigation pane, click Domain Names.
  3. On the Domain Names page, find the domain name that you want to manage and click Manage in the Actions column of the domain name.
  4. In the management pane of the domain name, click Back-to-origin.
  5. In the Back-to-origin Request Timeout section, click Modify.
  6. In the Back-to-origin Request Timeout dialog box, set Timeout Value.
    Set a timeout period for back-to-origin requests
  7. Click OK.
