# httpecho










The same thing as [`jmalloc/echo-server`](https://github.com/jmalloc/echo-server) **but HTTP requests are echoed as they are received**.

*Particularly useful for [http request smuggling vulnerability research](https://github.com/ariary/HTTPCustomHouse), malformed HTTP requests etc*

```shell

$ httpecho

# On another shell

$ curl -d "param1=value1&param2=value2" -X POST http://localhost:8888/ -H "Transfer-Encoding: chunked" -H "Content-Length: 8"

POST / HTTP/1.1

Host: localhost:8888

User-Agent: curl/7.58.0

Accept: */*

Transfer-Encoding: chunked

Content-Length: 8

Content-Type: application/x-www-form-urlencoded

1b

param1=value1&param2=value2

0

```
