Introduction
The variables of the rule engine allow you to dynamically extract and process data within request. These variables can not only store static values but also use for specific fields or information in the request, the value of which may change when processing each request. For example: the http.request.host variable, which can extract the hostname in each HTTP request. This capability enables the rule engine to handle more complex business logic.

1. The custom origin-pull request header carries the information of the country where the client IP address is located back to the origin.
﻿
2. Custom origin-pull request headers allow the origin server to collect and analyze which domains have been accelerated by Tencent's EdgeOne.
﻿
3. Custom Cross-Origin Request Policy: Allows cross-origin requests from domains specified in the Origin header of the request.
