Hi Rich, I don't have a solution at the moment but I'm seeing the same in our current code and wanted to pass some information on to John Caron who I think will have to solve the issue. John, I'm seeing in NetcdfDataset.isDODS() that a HttpUrlConnection is being opened to http://stellwagen.er.usgs.gov/models/gomoos/gomoos_20040329_cf.nc.dds and it is checking the response code and getting a 200. I'm not sure why since when I try it in a browser and look at the headers I see a 302 Not Found. Not sure where to go from here so I'll leave it up to you.
