Yes, it's the cocoon: protocol doing the magic - your message pipeline
is called internally which means within the same request. In order
to get the information about the uri of the real request (cinclude) in
the internal pipeline, the getServletPath method returns this
original value.

The getSitemapURI() method was added to the request object for exactly 
that purpose - use this whenever you want to compare the URI of the
