[Extension Name] org.apache.tapestry.request-decoder [Type] IRequestDecoder [Description] 
A request decoder is used to identify the actual server name, server port, scheme and request URI for the request. In some configurations, a firewall may invalidate the values provided by the actual HttpServletRequest (the values reflect the internal server forwarded to by the firewall, not the actual values used by the external client). A request decoder knows how to determine the actual values.
