Launching jws application outside firewall

Question

Hi all,
We have successfully deployed our application with JWS at a client site. We don't have any problems within the client environment, but we can't seem to provide home access to their users.
Client is using Cisco VPN Concentrator 3020 series and they give only WebVPN access.
We have tried many things but here is where we are stuck:
1. User goes to the website
2. Establishes a WebVPN session after entering the user/pwd
3. User enters the URL for the application
4. home.html goes through fine
5. JWS launch errors out with an exception.
Exception is 'missing <jnlp>'. When you look at the Launch File, you see an html page with fields for username and password entry. It seems like as JWS start creates a new connection to the secure website, it needs to authenticate it self. Unfortunately we don't receive the 401 http code, instead we receive an html form.
I would appreciate any ideas for dealing with this situation.
Thanks,

If your jnlp file contains the <offline-allowed> javaws will "attempt" to
download new jar files if it can read the timestamps from the net (and determine that new versions are needed) within a certain timeout (defaults to 1.5 seconds). If the timeout occurs the old version will launch, and the timestamp check will continue in the background. If the timestamp check then finds new files, it will simply flag this in the cache, so on the next launch it will be forced to download.
I don't see any reason why it should be any differant launching from browser or from Application Manager, unless that changes the timeing so the check just happens to work within the timeout.
