reload-metadata & multiple metadata providers

I think I get it now.

We have historically avoided reloading the metadata resolver service because for some our IdP's it would "overwhelm" Tomcat/shib to the point of being unresponsive (largely due to the size of the InCommon md aggregate -- md query should take care of that concern in the future though). Because we have separated the InCommon md entry in our "base" image with the id of "NebraskaShibbolethMetadata" from the other campus specific metadata entries we can now load the local metadata providers in the campus image with reloading "everything". In my particular case, the following command worked now that I'm using the correct id.

curl -k "https://localhost:8443/idp/profile/admin/reload-metadata?id=ShibbolethMetadata"

Reloading the metadata service is entirely different and would involve saying "reload-service".  It completely restarts the service including reloading all files.

Reloading metadata providers is about reloading one provider at the "level down" from that, so in your case you either have two files and that is the level at which you can reload or you have one file where the topmost element is a chaining provider.  Either way you cannot descend into the next level down

So if you had a single file looking roughly like this

<MetadataProvider type="chaining">
	<MetadataProvider type="chaining" id=" ShibbolethMetadata">
		<MetadataProvider type="chaining" id="NEFED">
	<MetadataProvider type="chaining" id="NebraskaShibbolethMetadata ">

And so on, you can reload NebraskaShibbolethMetadata an ShibbolethMetadata, but not NEFED.

Similarly if you had two files one for NebraskaShibbolethMetadata and the other ShibbolethMetadata 

Either way, you only get to chose from those two.

I suspect the team would entertain and RFE (if one was forthcoming) to look at the idea of allowing recursive descent into sub-providers, but a full fix might implicate the status page and gauges so it might blow up and not happen....
