We are trying to run a java applet on the Mac os X, panther, using the
Safari web browser which uses the default java jre version 1.4.2. The
mac network properties is set to go through a proxy server for all
protocols. The proxy server uses a basic authentication setting. The
request for the applet is done using the https protocol. The applet
is executed in a standard html file using the proper applet tags. I
should note that the applet does execute successfully when the html is
requested without a proxy. However, when the initial request is made
through a proxy, the safari browser prompts for the proxy
authentication information, as it should and then the java console
appears as safari attempts to load the java applet. However, the
applet does not load. When reviewing the Internet Information
Services logs, the initial request to the website via the proxy is
present, however the request for the jar file appears to have never
made it to the IIS server.

Does anyone have any ideas as to why the request is not going through?
Any help would be greatly appreciated.
