### Description
I want to redirect some requests to upstream servers, how should I do for
this case?
How can I refer to upstream server chosen by loadbalancer in uri field in
redirect plugin.
like this:
```json
{
"uri": "/test/index.html",
"plugins": {
"redirect": {
"uri": "$upstream_addr",
"ret_code": 301
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"127.0.0.1:80": 1
}
}
}
```
as demenstrated above, I want a variable like "$upstream_addr".
Thanks.
