How to proxy requests from client to another server

I am working on a mobile app that will get some information from 3rd party API. API only accepts requests from certain IPs, that's why I am trying to build a proxy server that will work like below:

A -> Mobile Clients (IP: 1.1.1.1)
B -> Proxy Server (IP: 2.2.2.2)
C -> 3rd Party API (myapisite.com/*)

Basically, every request from A to C needs to go through B since C only accepts requests from B's IP. I've tried to build it via HAProxy but couldn't manage with domain names. I need a routing mechanism like below:

HTTP requests to 2.2.2.2/myapi should be forwarded to myapisite.com/api
HTTP requests to 2.2.2.2/myotherapi should be forwarded to myapisite.com/otherapi

What would be the simplest solution? Right now, I am thinking about using Ubuntu as a proxy server.

Solution

    listen fe_http
  mode tcp
  timeout client  60s
