Status: VERIFIED DUPLICATE of bug 60304

(Core :: Networking: HTTP, defect)

Description

BuilId 2001102203 NT4
My company implemented proxy authentication yesterday.
Before that, we had proxy w/o authentication

the proxy is SQUID 2.4.STABLE1
Since yesterday, I'm unable to load any java applets, though I didn't
experience any problem with Java plugin before.

Hereafter are the steps:
1. Start mozilla from scratch
2. Home page being Mozilla.org, a password dialog is raised which
is auto filled. Type OK. Browser shows Mozilla home page. So far so good
3. Now, connect to the URL proposed or any URL containing an applet.
4. The applet start to load and then a new password dialog is displayed,
not from Mozilla, but from the proxy (well I suppose).
See attachment #1 [details] [diff] [review] for a screenshot of this window.
5. After filling it, the applet refuse to continue loading.
the java console shows the following
load: class WbIHApplet.class not found.

java.lang.ClassNotFoundException: java.io.FileNotFoundException:

Attachment #2 [details] [diff] shows a screenshot of the inside of the window area.
6. click the reload button to reload the page 
The applet still do not load with the following in the java console

Very important note: I have also IE5.5 and NS4.7 on my desktop and both
works normally with applets once the initial proxy authentication (step 2)
is done.

I mean with NS4.7 and IE5.5, there is no second authentication
window and it works fine.
