Nice article and the minimalist nature of LWP::Simple is really in the spirit of Perl (IMO). It also has a number of very handy features like being able to save a webpage to directly to a file... really useful for retrieving the biological data files that form the basis of my work (as they are stored as plain text).
in reply to Getting more out of LWP::Simple
With regards to exporting the user agent from LWP::Simple this is always a good idea. However it becomes essential (in that you need a ua of some kind and it would be silly to create another ;D) if you are behind a firewall. In my post Incase You Need to Use a Proxy with LWP I have included some code snippets to show how I used LWP::Simple from behind a firewall. This may be necessary for many who are stuck behind a corporate/instiutions firewall.
Hope that adds to the material. Arun
