If you use the version download protocol it only has to check the main 
jnlp file. I.e. if you specify versions for every resource referenced 
from the application jnlp file then WebStart can check if it has those 
versions without further reference to the server.

In addition the request for the application JNLP file will include the 
modification date of the version it already has. The server does not 
need to send the JNLP file content with the reply if the modification 
date is still current. Thus all that is required is a single round trip 
with negligible content when nothing has changed.
