重写请求头
这个功能目前仅在 Beta 版中提供。
在请求被转发到服务器前，Surge 可以修改请求头。
例子：
[Header Rewrite]
^http://example.com header-add DNT 1
^http://example.com header-del Cookie
^http://example.com header-replace User-Agent Unknown
每条规则包含 4 个部分：URL 正则表达式、行为类型、请求头里的哪个部分以及变量。T
像请求头中附加一条属性。

[Header Rewrite]
^http://example.com header-add DNT 1
