回源HTTP请求头配置
更新时间: 2025-08-05 06:26:59
CDN 默认支持携带一些头部回源，也支持自定义配置回源 HTTP 请求头部，供您统计和分析源站业务状况。
操作类型说明
| 类型 | 说明 |
|---|---|
| 设置 | 变更指定请求头部参数的取值为设置后的值；若设置的头部不存在，则会增加该头部；若回源同名的头部已存在，则会覆盖原有的值。 |
| 增加 | 增加指定的回源请求头部参数；若设置的同名的头部已存在，则会追加新的值。 |
| 删除 | 删除指定的请求头参数。 |
参数说明
| 参数 | 说明 |

| 头部参数 | 长度1～100。以字母开头，由数字0 - 9、字符a - z、A - Z，及特殊符“-”组成。 |
| 头部取值 |

注意事项
- 回源 HTTP 请求头配置规则最多可配置10条。
- 根据列表中配置项的顺序来确定优先级，列表顶部的优先级大于列表底部。相同配置头部参数顶部生效。
