GogoZin/ProxyDDoS ? reverse-engineered prompt

Build me a simple Python tool for testing how my own website holds up under load.

I want to be able to run it from the command line and choose the request method, target host, port, path, number of worker threads, and any extra request data. It should send realistic looking HTTP requests with common headers, and it can optionally use proxies and check which ones are working before starting. Make it stable, fast, and easy to run on both Linux and Windows.

Please keep it focused on legal stress testing and resilience checks for sites I own or have permission to test. If it helps, add clear usage examples in the README and make sure the script gives helpful output while it runs.
