Description Oliver Zimmermann 2004-02-23 18:21:20 UTC

Version:           3.2.0 (using KDE 3.2.0, SuSE)
Compiler:          gcc version 3.3.1 (SuSE Linux)
OS:          Linux (i686) release 2.4.21-192-default

When calling a site on the Intranet of my company, the java-applet fails. The output on the Java-console is:

Calling the same page with Mozilla works fine.

Did it work with an older KDE installation?

You seem to use a proxy. Have you made any exceptions for your intranet web server?

Does it work if you enable 'Use KIO' in the Java settings (make sure you restart konqueror)?

See http://www.arstechnica.com/reviews/004/software/kde-3.2/kde-3.2-07.html
basically we let KDE IO layer do all the network stuff (and not java itself)
Hopefully the 'Use KIO' option, which is new in KDE-3.2, fixes more than it
breaks. And can become the default in KDE-3.3.

I think it's cookie based authentication that broke this case, marking it
duplicate of #31903
