curl\_sh
========
_A User-Agent based proxy_

This nginx configuration will return `script.sh` if the user-agent matches "**curl**".
In any other case it will act as a reverse-proxy to `PROXY_PASS_HOST`.

### Usage

```sh
$ docker build . -t curl_sh
$ docker run -e PROXY_PASS_HOST=http://my_host:1234 --rm curl_sh
```
