Transport option not being respected by MDQ metadata provider.

[Krishna Mohan]

Hi All,

We have a service provider 3.0.4 on windows and trying to configure MDQ metadata provider using a webproxy.
We are not seeing the webproxy being utilized, when it tries to load metadata. Below is the configuration and the logs.

Did we miss something or is there a bug?

         <MetadataProvider type="MDQ" id="incommon" ignoreTransport="true" cacheDirectory="inc-mdq-cache"
maxCacheDuration="86400" minCacheDuration="60"
baseUrl="https://mdq.incommon.org/">
<TransportOption provider="CURL" option="10004">xxxx-webproxy.xxxx.internal:xxxx</TransportOption>
<MetadataFilter type="Signature" certificate="inc-md-cert-mdq.pem"/>
</MetadataProvider>
