[thredds] TDS initialization

[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Hi,

We're starting to put together some "big" server-side configuration 
catalogs (both with "lots" of dataset elements and "lots" of catalogRef 
elements).  We are wondering about the process TDS goes through to read 
the catalog when is starts.  What gets cached?  Does it have a way to 
know a referenced catalog is unchanged?  When do referenced catalogs get 
scanned?  And so on.

Is there some documentation or a flow chart on how TDS initializes itself?

Thanks,
Roland
