Hi Peter, Tim, The server at the URL below is running TDS 4.0.24 (2009-07-24). Our current release is TDS 4.2.3 (with 4.2.4 coming out soon). A lot of work has gone into the caching and updating code since 4.0. I would suggest you upgrade and see if that solves the problem you are seeing. Here is a link to some configuration changes/additions between 4.0 and 4.2: http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.2/UpgradingTo4.2.html Let us know if that solves the problem.
