-一段脚本，用于检测流量的属性值。当此脚本返回真值时，此规则生效。
-
-脚本语言为 [Starlark](https://github.com/bazelbuild/starlark)，它的语法是 Python 的子集。脚本接受一个全局变量 `attrs`，其中包含了流量相关的属性。
+一个 json object，键名字和值皆为字符串，用于检测流量的属性值。当 HTTP headers 包含所有指定的键，并且值包含指定的子字符串，则命中此规则。大小写不敏感。
 
 目前只有 http 入站代理会设置这一属性。
 
 示例：
 
-- 检测 HTTP GET：`"attrs[':method'] == 'GET'"`
-- 检测 HTTP Path：`"attrs[':path'].startswith('/test')"`
-- 检测 Content Type：`"attrs['accept'].index('text/html') >= 0"`
+- 检测 HTTP GET：`{":method": "GET"}`
+- 检测 HTTP Path：`{":path": "/test"}"`
+- 检测 Content Type：`{"accept": "text/html"}"`

-A script used to detect the attribute values of the traffic. When this script returns a truthy value, this rule takes effect.
-
-The script language is [Starlark](https://github.com/bazelbuild/starlark), which is a subset of Python syntax. The script accepts a global variable `attrs`, which contains traffic-related attributes.
+A json object with string keys and values, used to detect the HTTP headers of the traffic. It matches when all specified keys exist in the header and corresponding values are a substring of the header value, case in-sensitive.
 
 Currently, only the inbound HTTP proxy sets this attribute.
 
 Examples:
 
-- Detect HTTP GET: `"attrs[':method'] == 'GET'"`
-- Detect HTTP Path: `"attrs[':path'].startswith('/test')"`
-- Detect Content Type: `"attrs['accept'].index('text/html') >= 0"`
