Real client IP header allows you to create a custom origin-pull HTTP request header that carries the real client IP information.
Log in to the EdgeOne console. Click Site acceleration > Network optimization on the left sidebar.
On the network optimization page, select a site and click to enable the "Real client IP header" feature.
In the pop-up window, enter a header name, such as Tencent-Client-IP, and click Save.
The configuration on this page takes effect for all requests of the selected sites. To create a custom configuration for subdomain names or request paths, you can switch to Rule Engine.
