java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.0-beta3-b84)
Java HotSpot(TM) Client VM (build 1.4.0-beta3-b84, mixed mode)

Full Operating System Version :
Microsoft Windows 2000 [Version 5.00.2195]



Extra relevant system configuration :
During the JRE installation, I let the installation
install itself as the default JVM for IE and Netscape.
Thus, the JRE is used for pages with <APPLET> tags.

A description of the problem :
I'm a customer of Datek - an online broker. Datek has
a very sophisticated applet called "Streamer" for getting
realtime quotes. The applet loaded/worked fine under both
IE and Netscape until I made JRE 1.4b3 the default JVM. Now
when I go to the page, the JRE starts loading the applet
but the console continues to report:
java.io.IOException: Caching not supported for
http://streamerapp.datek.com/applets.jar

Steps to follow to reproduce the problem :
1. Get a login on www.datek.com and start the Streamer
applet.

When I did a keyword search for "Caching not supported" on
the Javasoft site, I saw that one other person has posted
a message (11/09) that he had this problem on one of his
applets as well.
Sorry - I can't give you my brokerage login to reproduce :-)

Expected versus actual behavoir :
Apparently, <APPLET> doesn't quite work the same way under
the JRE as it used to natively.

Error messages/stack traces that occur :
