Having looked at the LWP::UserAgent and LWP::Protocol::HTTP code, I think it should be doable to edit them to add support for the proxy either being an array ref, or a string of proxies chained with some convenient dividers (eg |). The idea is that whever you see a reference to a proxy, you just loop through the proxies and do what you do for all of them. Having scanned it, adding chained proxy support to HTTP looks doable (just a handful of lines in a couple of modules - grep for "proxy" and do "perldoc -l LWP::UserAgent" to find where it is on your system) and probably a lot easier than writing significant new code. It is distributed under the same terms as Perl, those are pretty generous so legal issues are likely not a problem for you.

If don't think your Perl is up to it, ask on the appropriate list and you likely will find someone else who can. (The speed with which they add features for you might be affected by financial encouragement...)

If you then contribute that back, and a lot of people will suddenly be able to easily use chained proxies in Perl if they need it. :-)

PS My comment about chained proxies was not a statement that they aren't useful, just a comment about where I happened to have seen them before.
