in thread Slashdot Headline Grabber for Win32

Well, my first post on
( and I FSK it up.... sheesh! )

I am working from behind a corporate firewall, so I tried the LWP example above with my proxy info, and am getting:

Protocol scheme: '' is not supported.
along with what looks like a 501 response in the debugger.

I tried this with a couple of different URLs and got the same result, so I suspect it may be the proxy setup. Any ideas?

Just to confirm:

My proxy settings in Netscape show

so I used:
#set up your proxy here
$ua->proxy('http', '');

I tried both 80 and 8080 for ports, with the same result.

Any advice appreciated.

    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 ''. 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 - 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:
    return "PROXY";
    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.

      Netscape wouldn't give me the source right from the URL, so I went with using a quick LWP script like you suggested, and nabbed the file.

      Inserted address and port, and now it works nicely.

      I don't have a proxy at home, so last night I ripped it up to grab news headlines from slashdot, cnn, antionline,, and yahoo news and spit them all out on a webpage. Not that hard, but the first time I ever got it to work right.
