[Zope3-dev] Redirects

This still feels wrong to me: in your example document_view is not
(necessarily) the logical result of document_edit.  It especially
isn't the result if you're passing random parameters to it:
document_view will need to know about all possible transitions to that
state, which in my mind violates the principle of loose coupling.

I would much prefer an explicit method, document_edited for example,
which then *called* document_view or whatever.

Ah yes, sorry about this.  I expected RFC2068 to have a note about its
obsolescence.
