原文摘录

摘自原文(3808 字符中的一小部分)
**Summary:** The `llhttp` parser in the `http` module in Node 16.3.0 ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) when a Node server is put behind an Apache Traffic Server (ATS) 9.0.0 proxy.
原文中的代码
GET / HTTP/1.1
Host: localhost
Transfer-Encoding: chunked
