Different proxies to the same site at different urls?

Question

proxy

How can this be implemented. That is, you need such a local anonymizer so that it builds tunnels through different proxies to the same site using different links.
For example, we have a prokey list and then:
127.0.0.1/1/http://site.ru - through 1 proxy in the list
127.0.0.1/2/http://site.ru - through 2 proxies in the list
127.0.0.1/n /http://site.ru - through n proxies in the list
