How do I handle HTTP status codes that indicate errors (e.g., 404, 500) in Go?

After making the HTTP request, check the `resp.StatusCode` field. If it's outside the 200-299 range, it indicates an error. Handle these errors based on the status code. For example, a 404 (Not Found) might indicate a missing resource, while a 500 (Internal Server Error) suggests a problem on the server. Log the status code and potentially retry the request with exponential backoff for server errors.
