A Pipeline can both forward requests internally (to another pipeline) or send explicit redirects back to the client.
The redirect-to element must have one of these 2 attributes:
resource -- the resource to forward to
uri -- the URI to redirect to.
With the resource attribute set, pipeline processing continues with the named resource. In recent releases (2.1.1 and later - I haven't looked at earlier versions), this is deprecated in favour of call.
With a uri attribute, a HTTP redirect response is send to the client. The pipeline processing ends. In this case, three Boolean parameters may be set. They all default to false.
global -- ???
permanent -- set true to make the HTTP redirect permanent
session -- indicates whether the session should be maintained during the redirect
