I think that the problem is that your company uses a proxy configuration script.
If you check your Netscape proxy settings you should have the 'Automatic proxy configuration' option enabled and the 'Configuration Location (URL)' set to 'pset.tgw.canon.co.jp/proxy.pac'. If so my guess is correct: your are using an automatic proxy configuration script.
You may download the proxy configuration script with a browser going to the URL http://pset.tgw.canon.co.jp/proxy.pac - or with a simple perl script that uses LWP and gets that URL :-).
The script should not be too complicated to read: there should be a function that returns a proxy, more or less like this:
the return value may be different if you are trying to get corporate intranet URLs or Internet URLs (for corporate intranet URLs you may have something like return "DIRECT").
So all you have to do is find out in the proxy.pac the IP address (or the name), and the port of the real proxy your company is using to access the Internet, and then use this same proxy and port in the perl script.
I hope this works. If you have problems, ask me, please.
