Honestly, I’d recommend using a VPN instead of a linux curl proxy for secure requests. But if you’re set on proxies, check out Squid Proxy. It’s super configurable and works well with curl.
For testing, just use `curl -x http://proxy-server:port http://example.com` and see if you get a response. If it times out, the proxy might not be working.
