Using JDK1.3.1 and today's trunk worksforme on WINTT.

I'll have our QA try it on WINME.

Applet works well behind proxy/firewall on WinME.

Mozilla 0.9.2 and 0.9.3
JDK 1.3.1

Hello,
sorry. The mozilla-win32-installer-sea.exe (20010808) is still not working
with Windows NT and SQuid. If you turn on user authentication in SQUid
2.3STABLE3 the Java subsystem is broken. It works works Netscape 4.7x and IE 5.x.

Bye
  Rainer Tammer

P.S.: We use two cascaded proxy servers.
First proxy on the firewall and second proxy on the internal network. The second
proxy uses user authentication. If I turn off the user authentication it works.

Hello,
additional info:

I checked our log files ... if you try to load the clock applet you can see
that no user info is transmitted. If you use Netscape 4.7x the user info is
transmitted.

Mozilla nightly on Win32:

Hi Oleg,

Can you replicate the test environment proposed by tammer? Particularly the
being able to check the log files for user info being sent or not?

Tested today under WinME and RH Linux with jdk1.3.1
Used squid-2.4.STABLE1 as password protected firewall.
Under WInME(mozilla 0.9.2 & 0.9.3) results are exactly the same as in bug
report:
 - Security exception on console
 - Applet isn't loaded
Under Linux and mozilla 0.9.2 all works fine:
 - Additional authorization window appears during applet startup and
   ask about proxy user/password
 - Applet loads and render well without of any exception.

Attached please look at part of squid logs for Linux and WinME and note,
that user isn't transfered for WInME

Since the java plugin handles HTTP requests originating from applets, I'm going
to re-assign this one to JPI.


------- Additional Comments From ###@###.### 2001-08-10 19:37 -------

assign to jmelvin.

reassign to Jim Melvin.

Marking invalid. I'll file this in bugtraq.
