That is what

push @{ $ua->requests_redirectable }, 'POST';
[download]

Is supposed to take care of
(I have even gone in and edited the library to force a return of 1 from redirect_ok and the redirect doesn't occur,
I have also put print output in there to make sure the push does what it is supposed to and the function is returning 1).
Am I coding this wrong or does it just not work.
