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.


- 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?

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

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  Huh

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  Angry
