## Créer une `PNGStreamingResponse` personnalisée { #a-custom-pngstreamingresponse }

Dans les exemples ci-dessus, les octets de données étaient diffusés, mais la réponse n'avait pas d'en-tête `Content-Type`, le client ne savait donc pas quel type de données il recevait.

    }

    public void setUserAgent_Equal(String userAgent) {
        setUserAgent_Term(userAgent, null);
    }

    public void setUserAgent_Equal(String userAgent, ConditionOptionCall<TermQueryBuilder> opLambda) {
        setUserAgent_Term(userAgent, opLambda);
    }

    public void setUserAgent_Term(String userAgent) {
        setUserAgent_Term(userAgent, null);
    }

        this.updatedTime = value;
    }

    public String getUserAgent() {
        checkSpecifiedProperty("userAgent");
        return convertEmptyToNull(userAgent);
    }

    public void setUserAgent(String value) {
        registerModifiedProperty("userAgent");
        this.userAgent = value;
    }

  val android5 = sslLabsClients.first { it.userAgent == "Android" && it.version == "5.0.0" }
  val android9 = sslLabsClients.first { it.userAgent == "Android" && it.version == "9.0" }
  val chrome33 = sslLabsClients.first { it.userAgent == "Chrome" && it.version == "33" }
  val chrome57 = sslLabsClients.first { it.userAgent == "Chrome" && it.version == "57" }
  val chrome80 = sslLabsClients.first { it.userAgent == "Chrome" && it.version == "80" }

Dans ce cas, la session de base de données serait conservée jusqu’à la fin de l’envoi de la réponse, mais si vous ne l’utilisez pas, il ne serait pas nécessaire de la conserver.

Voici à quoi cela pourrait ressembler :
