Does this SDK client support empty proxy username and password? #2559

Hello, I would like to ask if azure-iot-sdk-c can be connected to via a proxy server that does not require a username and password?

====

        proxy_options.host_address  = proxy_options_->host_address;
        proxy_options.port          = proxy_options_->port;
        proxy_options.username      = proxy_options_->username; // <-- This is empty string ""
        proxy_options.password      = proxy_options_->password; // <-- This is empty string ""

        IoTHubDeviceClient_LL_SetOption(device_ll_handle_, OPTION_HTTP_PROXY, &proxy_options);

====

Thank you.

Have you tried setting these to NULL? By setting these to a string value, the SDK will transmit these values, even if they are empty strings.
