Facebook provides a custom tag to accomplish a redirect within the Facebook canvas - Fb:redirect (http://wiki.developers.facebook.com/index.php/Fb:redirect
).
I ended up doing a custom IRequestTarget implementation for this purpose, and thought I'd share what I came up with here. Please bear with my very limited experience with Wicket, I was just happy to get it working for my simple need. Feel free to edit/add to this as you see fit.

String redirectUrl = processor.getRequestCodingStrategy().encode(
requestCycle, this).toString();
Page page = new RedirectPageFBRedirectPage(redirectUrl);
page.renderPage();
