Function writeBadRequest

pkg/agent/proxy/incoming/http.go:1005–1007

writeBadRequest is the client-side counterpart to writeBadGateway: 400-class so the failure isn't misattributed to the upstream by downstream proxies / monitoring. Used when we detect a malformed or truncated request from the downstream client (e.g., Content-Length mismatch during replay-safety pre-

(c net.Conn)

// or truncated request from the downstream client (e.g.,
// Content-Length mismatch during replay-safety pre-buffering).
func writeBadRequest(c net.Conn) {
	_, _ = c.Write([]byte("HTTP/1.1 400 Bad Request\r\nContent-Length: 0\r\nConnection: close\r\n\r\n"))
}

// handleHttp1ZeroCopy handles HTTP/1.x connections in normal (non-sync) and
// sampling modes.
