I'm not clear, are
you trying to build a page that would display download progress in such fashion.. or are you instead trying to download a large file, for example?
There are many tools out there to aid in downloading large files off the web. If you are using the Firefox browser, you may find some of the download
extensions useful as well.
But if you are trying to build a script to fetch files the
Bundle::LWP module could help as is also explained in this
post. Whereas this
post also explains how to download multiple files at once.
