Yes, whoops, forgot about that (slept since then). Yes, the filename
is passed on to LWP::UserAgent,
http://search.cpan.org/~gaas/libwww-perl-5.826/lib/LWP/UserAgent.pm#REQUEST_METHODS
IIRC, there was an odd issue that popped up when passing the filename
onto get(), but I so recall append working correctly at one point.
Let me se what I can work out.
