In a similar question: LWP::UserAgent timeout, I have suggested HTTP::Async which downloads a list of urls and reports back when done. If you want a list of urls to be fetched in parallel, there is LWP::Parallel::UserAgent. The latter will block until all urls are fethced. But they are fetched in parallel, so bandwidth and server allowing, it will probably be faster than sequential download. The former will not block, you check on progress by asking it.

However, the bottomline on answers on said question, and in this one too, is that you need to familiarise yourself with Tk::IO because:

I'd just add that, in either case, given that you are dealing with a GUI, it's usually a best practice to use a separate thread for the UI events processing and another for the processing (markong):

So, elevate yourself this festive season with multi-threading...
