[thredds] Turning off static file caching

["Drach, Bob" <drach1@xxxxxxxx>]

The TDS configuration documentation states that to turn off static file 
caching, the directive is:


<Catalog>
   <cache>false</cache>
</Catalog>


Does this directive go in threddsConfig.xml, or in the catalog(s) themselves?


Thanks,


Bob D.
