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:

only when there's certain, pre-defined keyword in the URL, traffic must be routed via a proxy.
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

Maybe have two cases:
For the (matched keyword) case, something like this: https://serverfault.com/questions/729232/reg-exp-for-url-in-haproxy

For the (random routing) case, something like: https://www.haproxy.com/blog/haproxy-configuration-basics-load-balance-your-servers

I am a little confused on your question, though. It sounds like you maybe want 3 cases? Can you try wording it differently?

Cool, I think that first link will work for you. Then you can just 'redirect' for the no-keyword case: https://www.haproxy.com/documentation/haproxy-configuration-tutorials/http-redirects/

Remember, SSL/HTTPS does encrypt the URL path, so if the final website requires HTTPS, your proxy will need to have its certificate trusted by your clients
