Perhaps this would work
Create an environmental object called Mode
public interface Mode {
public String getMode(); // facebook or normal
}
Use tapestry's URL rewriting to rewrite http://myapp/facebook/page to
http://myapp/page (see
http://blog.tapestry5.de/index.php/2010/09/06/new-url-rewriting-api/)
As the URL is rewritten, it pushes a mode onto the environment (either
"facebook" or "normal")
@Inject
Environment environment
String mode = getModeFromURL();
environment.push(Mode.class, new ModeImpl(mode));
When rendering links, use Environment.peek() to get the Mode from the
environment and add the mode to each link URL if necessary.
Components and Pages can then use the @Environmental annotation to inject
the mode to determine which styles to include
Then you get normal browsers to access http://myapp/page and facebook to
access http://myapp/facebook/page
