How can I write a Ruby script to automate the process of brute-forcing a login form

Question

I’m learning about ethical hacking techniques, and I’m trying to create a simple Ruby script that automates brute-force attacks on login forms for testing purposes. I’ve identified a vulnerable test server and I want to experiment with different combinations of usernames and passwords, but I’m not sure how to properly send HTTP requests in Ruby or handle form submission in the script.

Could someone guide me through writing a basic Ruby script to brute-force a login form? I’d also appreciate any advice on rate-limiting issues or how to avoid being detected by security mechanisms.
