Did you read the documentation? Or shmem's comments? You need to start making some effort. See LWP::UserAgent for details of what $agent->proxy(['http','ftp'],'http://search.cpan.org/~gaas/libwww-perl-5.808/lib/LWP/Simple.pm'); does, and what a proxy server is, since you don't seem to understand this concept either. Once again, well done for not reading the replies you get to your questions.
