Explain status codes
Quest: explain-status-codes
Mission
Explain 200, 404, and 502 in one short answer.
Commands You Will Use
curl -I
Steps
- Read the status-code card.
- Use
curl -Ion a working page. - Think through what missing content and bad backend proxying would return.
- Answer the guide with all three meanings.
Hints
200means success.404means missing path.502means a proxy could not obtain a usable backend response; an unreachable backend is one possible cause.
If Check Fails
Explain all three meanings in your own words: 200 is a successful request, 404 means the requested resource was not found, and 502 means a proxy could not obtain a usable backend response. Numbers or a keyword list alone do not satisfy the check.
