Re: [thredds] over written file has old global attributes

Hi jean: '
My guess is you are getting the cached information, which hasn't been updated. You can set the frequency of update in the catalog xml file. Also, usually if you touch the file (i.e. do something that causes to Thredds to access the data( that usually also updates the info.

I have a set of netcdf files that are being accessed via OpenDAP and are regularly overwritten. Most of the files, 29 sets of 31, update correctly 
but in 2 file sets the "Global Attributes" don't update to the new
information although the "data" does. "ncdump -h" shows the correct
information, :history = "MOST v2.080 11-05-2007  16:09:22" ;
              :title = "Aleutian-Cascadia: Mwt 8.4, 21.00*b65" ;
  in the headers but when I look at it in a browser,
http://sift.pmel.noaa.gov/thredds/dodsC/data/crescent_runup_ha.nc.html
I see the old file attributes,
history: "MOST v2.080 11-05-2007  11:49:33"
title: "Aleutian-Cascadia: Mwt 8.5, 29.00*b25".
If I restart tomcat then the correct information shows up.
I'm new at thredds so I may very well be doing something stupid but I
could find no information. Below is the change I made to
$tomcat_home/content/thredds/catalog.xml. Any suggestion?
Thank you, Jean
