Automatic proxy configuration can't work with Plug-in 1.3.1beta in NS6

When NS6 is used with automatic proxy configuration,
any url can not be opened.

Tested with NS6 and j2re build 1.3.1beta-b13 and reproduced on solaris8 sparc, solaris7 x86, Windows98 and RedHatLinux6.2J.


To reproduce,

Go to the url blow and excute test case 2 for auto proxy using file and
test case 3 for auto proxy using http with NS6.0.

<NOTE>I use the automatic proxy configuration file including the lines below located at http://javasoft.japan/~tokunaga/eng2.pac for our enviroment.


function FindProxyForURL(url, host) {

        return "PROXY webcache:8080";
}


Tested with NS4.7 and j2re build 1.3.1beta-b13 on Solrais7 x86 and Windows98:

1)Using http, a dialog comes up and says as below;
The automatic configuration file is not of correct type:
http://javasoft.japan/~tokunaga/eng2.pac
Expected MIME type of application/x-javascript-config or application/x-ns-proxy-autoconfig.
Use the configuration from the previous session instead?

2)Using file, NS4.7 works well and java applets can be excuted.
