# HTTP 处理

Surge 包含了多个用于修改 HTTP 请求和响应的功能，其处理管线 (pipeline) 的顺序如下：

1. URL 重写 (URL Rewrite)
2. 请求头重写 (Header Rewrite)
3. 请求体重写 (Body Rewrite)
4. 脚本处理 (Script Processing)

其中，脚本处理只能被一个脚本修改，而如果匹配到多个其他重写规则，它们将按顺序生效。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://surge.mitsea.com/http-processing.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
