This topic describes how to set the origin request timeout period. Specifically, the period of time in which CDN nodes wait for back-to-origin requests. The default timeout period is 30 seconds. Note that if a CDN node does not receive any requests from an origin within the specified timeout period, the CDN node disconnects itself from the origin.
