How to enable server side dns (rdns)?

[T-256]

simple request to github.com via http outband proxy get result as this:

b'CONNECT 140.82.113.26:443 HTTP/1.1\r\nHost: 140.82.113.26:443\r\nUser-Agent: Go-http-client/1.1\r\nProxy-Connection: Keep-Alive\r\n\r\n'

what actually need in server side: (server should resolve hostname)

b'CONNECT github.com:443 HTTP/1.1\r\nHost: github.com:443\r\nUser-Agent: Go-http-client/1.1\r\nProxy-Connection: Keep-Alive\r\n\r\n'

outbound:

"outbounds": [
        {
            "protocol": "http",
            "settings": {
                "servers": [
                    {
                        "address": "127.0.0.1",
                        "port": 7080
                    }
                ]
            },
            "tag": "http_out"
        }
    ]
