# HAProxy - JA4H HTTP Client-Fingerprint - Lua Plugin

----

You need to run HAProxy 2.9 or higher to use this plugin!

If the needed features are not yet available in your version - it will fail with the error `attempt to call a nil value (method 'req_cook_names')`

Test it: [fingerprint.oxl.app](https://fingerprint.oxl.app)

### Testing

Example:
```
FINGERPRINT
ge20cn16enus_38f13b2c1334_1b82fc6e2b78_60837532b357

DEBUG
ge_20_c_n_16_enus_accept,accept-encoding,accept-language,cache-control,cookie,host,priority,sec-ch-ua,sec-ch-ua-mobile,sec-ch-ua-platform,sec-fetch-dest,sec-fetch-mode,sec-fetch-site,sec-fetch-user,upgrade-insecure-requests,user-agent_abc,def_abc=test,def=me
```

#### Docker

If you prefer to use Docker, the manual steps can be skipped.
Run the docker container from the project root and access http://localhost:6969

```bash
docker compose -f test/docker-compose.yaml up --build --watch
```

`--watch` will automatically rebuild the container on changes

#### Local

**WARNING**: You need to run a version of HAProxy >=2.9 or `master`

* Run: `bash test/run.sh`
* Access the test website: http://localhost:6969/
* Or query the API: `curl -v https://localhost:6969/api`

```json
  {
    "fingerprint": "ge11nn14enus_1e32c07f0ac0_000000000000_000000000000",
    "details": "ge_11_n_n_14_enus_accept,accept-encoding,accept-language,cache-control,host,sec-ch-ua,sec-ch-ua-mobile,sec-ch-ua-platform,sec-fetch-dest,sec-fetch-mode,sec-fetch-site,sec-fetch-user,upgrade-insecure-requests,user-agent__"
  }
  ```
