Nginx重写位置

Question

我有一个具有以下配置的nginx服务器：

server {
    location /foo/ {
        proxy_pass https://192.168.0.21:6443;
    }

    location /bar/ {
        proxy_pass https://192.168.0.21;
    }

    location /other/ {
        proxy_pass https://192.168.0.21:7443/;
    }

}

我需要的是

https://my.domain.com/foo/rest_of_url-> https://192.168.0.21:6443/foo/rest_of_url

https://my.domain.com/bar/rest_of_url-> https://192.168.0.21/bar/rest_of_url

https://my.domain.com/other/rest_of_url-> https://192.168.0.21:7443/else/rest_of_url

我应该如何配置服务器？
