Webstart caching

[appel]

I'm really bothered by the fact that Java Webstart caches my files.

I am updating my game files frequently but Java Webstart does not detect many changes.

E.g.

- Updates to splash image not detected
- Updates to icon images not detected
- Adding a jar file to the jnlp file is not detected


Isn't there a way to FORCE webstart to redownload all files each time it runs a jnlp, and also redownload the jnlp? In effect, turn off ALL caching?

well, isnt there a version thing you can do? or is that just applets....

A thread on CodeRanch suggests that the HTTP Last-Modified header is what Webstart pays attention to.

Great, having to use some sort server trickery. Thanks Sun!

I've been having some trouble with this too.

Sometimes the webstart cache won't open so I can't clear the jnlp file, it just freezes 

Also, firefox caches the old jnlp file so even when I clear the webstart cache. After changing the jnlp file on my server, firefox still serves up the old jnlp file! So I have to clear  both the webstart cache and the firefox cache 

AND MERRY CHRISTMAS TO EVERYONE!
