New Revision: 376889
URL: http://svn.apache.org/viewcvs?rev=376889&view=rev
Log:
Refactor the configuration of remoting support into a helper class so that
it can be used from more than one place. Call it from XhtmlHelper if the
very first thing that happens is a non-Faces request forwarding to a
Faces response.
