How to make HAProxy redirect traffic via a certain sub-proxy depending on URL? (sopuli.xyz)

I have a server (S-1) with HAProxy and a number of residential proxies (PR-s) as login-passwords-port. There're multiple users who will connect to the internet via S-1.

I want to have HAProxy to forward incomming traffic of the users via a random proxy amoung PR-s with 2 conditions:

  1. only when there's certain, pre-defined keyword in the URL, traffic must be routed via a proxy.
  2. In all other cases, it must go to a requested resource directly as is, without a proxy

How would I implement this?

(1) client -> HaProxy -> if keyword --> sub-proxy (random) -> website

(2) client -> HaProxy -> if no keyword --> website

In your HAProxy config (like in this example), it's checked from top to bottom. So your top-most frontend case should be the one that checks for the special keyword case. Then, if it doesn't match the keyword, HAProxy will continue going down the list until it finds a frontend that does match. So your second frontend should match for everything, because if it doesn't find a match, HAProxy shows an error
