A load test that hits only the home page at a constant rate says little about how a system actually behaves under real load.

Upload forms rank among the most dangerous entry points in web applications, because attackers craft files specifically to pass every superficial check. Relying solely on file extension and content type opens the door to web shells and executable code.
