500 Can't connect to xtra.co.nz:80 (Bad protocol 'tcp') - Works on Command line but not via the browser

I have a little bit of a funny one here for you: (It's not that funny for me though!!)

If I run this perl file from my command line it works but if I run it via a cgi-bin directory on my browser I get an error (CODE and ERROR below).

I've checked my protocol file and it has the following (included below). - As far as I can see that is fine. (C:\WINNT\system32\drivers\etc\protocol).

I've tried it on an XP machine and a Win 2000 machine.

Does anyone know why? or do you have another way to read in the contents of a web page?

Thanks in advance
