Changes since 1.00:
-- when internally redirecting a URL, perlbal advertises
that it supports persisent HTTP connections now,
and caches those sockets for 5 seconds. (not configurable)
useful under load, otherwise you waste all local ports
on a machine
-- ditch dependence on IO::SendFile. do it ourselves (1 line)
with perl's syscall function
-- add doc/* and conf/* to MANIFEST fileThat last item is probably the most important to you, the potentially interested user: I accidentally forgot to include the example config files in the last release.
