{
"uri": "*",
"hosts": ["foo.com"],
"methods": ["PUT", "GET"],
"enable_websocket": true,
"upstream": {
"type": "roundrobin",
"nodes": {
"httpbin.org": 1
}
}
}'
```
2. have a try with normal request
```
curl -i http://127.0.0.1:9080/ip -H "Host:foo.com"
```
It will be success.
```

{
"origin": "172.19.0.1, 114.220.17.103"
