Okay I have copied the exact code from the above, included the POST in the namespace.
I still get an error that I don't understand

Can't locate object method "url" via package "HTTP::Headers" at /opt/local/lib/perl5/site_perl/5.005/HTTP/Message.pm line 186.

Can someone PLEASE help with this?
I am using perl 5.005_02 built for PA-RISC1.1
