Tony -
Not sure WHY not allowing redirects on POSTs is the default, perhaps
someone else on the list can help. I do know that the code snippet I
sent works for me. The man page says something like "subclasses might
want to override this".
I beleive I found the solution of the redirect_ok override on an
archive of the libwww list.
However changing the request method was something I had to discover by
experimentation. The problem I was having was that when I submitted a
certain form, it would go through several iterations of a redirect
loop and end up back at the same page I started from, whereas any web
browser would handle it correctly. I ended up using lynx compiled
with verbose logging and comparing the logs by hand. (ouch)
