Heh, this reminds me of the discussion a few days ago, where I was
criticized for saying: "Don't use Internet Explorer and you won't incur
the IE/Cocoon/PDF problem." Now we're saying: "Don't use redirects and
you won't incure Cocoon2's redirect problem." :-)

Using exceptions to control program flow? I think they should be
reserved for error-handling.

I'm not necessarily a big fan of redirects, but there is no other way
currently to control web program flow and now Cocoon2 is taking that
away as well :)
