in reply to WWW::Mechanize follow meta refreshes

$mech->content() =~ /<meta http-equiv="refresh" content="0;url=([^"]*) +"/; my $url = $1;

LanX open (You are not allowed to open to a command that pipes both in and out, but see IPC::Open2, IPC::Open3, and Bidirectional Communication with Another Process in perlipc for alternatives.)
[jdporter]: IPC::Open2, I guess
[jdporter]: yes, that
