func wafProtection() func(http.Handler) http.Handler {
	cfg := coraza.NewWAFConfig()
	cfg = cfg.WithErrorCallback(wafLogError)

	cfg = cfg.
		WithDirectives(`
			Include @owasp_crs/REQUEST-911-METHOD-ENFORCEMENT.conf
			Include server/owasp/rules.conf
		`).
		WithRootFS(mergefs.Merge(wafrules.FS, io.OSFS))

	waf, err := coraza.NewWAF(cfg)
	if err != nil {
		log.Fatal(err)
	}

	return func(h http.Handler) http.Handler {
		return wafhttp.WrapHandler(waf, h)
	}
}

func wafLogError(error types.MatchedRule) {
	fmt.Println(error.ClientIPAddress())
}

clientIpAddress always return 127.0.0.1
