The request elapsed time is greater than the timeout set on the target endpoint properties

[Giupo]

Hello, 

in the ProxyEndpoint I have:

    <HTTPProxyConnection>
        <Properties>
            <Property name="api.timeout">10000</Property>
        </Properties>
        <BasePath>/nag-test</BasePath>
    </HTTPProxyConnection>

and in the TargetEndpoint I have:

<HTTPTargetConnection>
        <Properties>
            <Property name="connect.timeout.millis">2000</Property>
            <Property name="io.timeout.millis">2000</Property>ì
        </Properties>
        ....
    </HTTPTargetConnection>

Our backend is offline, so we expect to have a timeout after 2 seconds, but currently on Postman I have:
503 after 6.84s
503 after 6.15s
503 after 6.33s

Could you help us make sure that the timeout received by the client is the same that is set up in the proprieties?
