That is why I installed a callback when I implemented it :-)
Basically a developer registers a callback for 301, 302 and 307 by
issuing the command libURLSetFollowRedirectCallback. libURL then sends
the message and the developer returns a value. If it is "redirect"
then libURL redirects. If it is "get" then libURL fetches the new URL
using "get". Any other value performs default libURL behavior which
returns "socket closed before end of file".
