Request target that is not a Wicket resource. For example, such a resource could denote an image in the web application directory (not mapped to a Wicket servlet). NOTE: this target can only be used in a servlet environment with {@link org.apache.wicket.protocol.http.WebRequestCycle}s.
NOTE: this class is a wrapper around {@link ResourceStreamRequestTarget#ResourceStreamRequestTarget(WebExternalResourceStream)}, and kept for compatibility purposes.
