By the way, you can't do that in 1.1. After startup the configutation is frozen
(and ActionMapping.addForward doesn't exist anymore).
In 1.0.2, Struts will examine the redirect attribute and, if it's set to true,
will then examine the path attribute to see if it starts with a "/". Only if it
does is the context prepended to the path. So, in 1.0.2 it looks like Struts
behaves the way wolfgang expected. In 1.1, however, the path attribute is
interpreted as strictly module- or context-relative. In other words, the
context is *always* prepended to the path. I'm not sure if this was driven by
the sub-module feature, but it's one of those places where the behavior has
changed.
