       $ua->requests_redirectable( \@requests );  # to set
           This reads or sets the object's list of request names
           that "$ua->redirect_ok(...)" will allow redirection
           for.  By default, this is "['GET', 'HEAD']", as per
           RFC 2068.  To change to include 'POST', consider:

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