If you're on a *nix box, you could use a tool like curl or wget if you're just doing a one-off. If you want to write some perl code, or are planning on doing something with the data in perl after fetching it, you might want to use LWP::UserAgent to get the URL, then write the data to a file.

When your only tool is a hammer, all problems look like your thumb.
