problem with THREDDS server 4.0 beta

[Nathan Potter]

Dennis,

Um... I suspect James' answer isn't addressing your problem. It is  
likely that the problem is probably with caching. Ethan Davis alerted  
me to it this week, and I have patched the Server4 code. Essentially  
the THREDDS responses are getting cached by your client and Server4  
is erroneously reporting that the last modified date is remaining  
unchanged despite your alterations to the catalog files.

We hope to have another beta release this week that will patch that  
and the problem you reported earlier regarding Tomcat hanging after a  
BES crash.
