Re: TDS Subsetting Service

Hi Eric:

It looks like you are using some old documentation, if you can point me to it, 
I will remove/fix it, and I will send you some new docs.

I think the short answer is that you want to change:

 <service name="subsetServer" serviceType="NetcdfServer"  
base="/thredds/ncServer/" />

   to

 <service name="subsetServer" serviceType="NetcdfService" base="/thredds/ncss/" 
/>
