How to avoid java applet caching

If you ever faced with Java applet development you've already noticed annoying caching. Applets could be cached almost everywhere - even on your HTTP proxy. The only real way to clean up cached java applets that I know is:

1. Turn of proxy usage in web browser
2. Clean up browser cache
3. Close any java program
   
4. Delete java cache from the computer you work on: for example, on Windows, remove directory
   

   %Documents and Settings%\%your_user_name%\Application Data\Sun\Java\Deployment

   If the step 3 haven't been executed you may not be able to delete this directory.
