Description

We have exceptions that restart a response and go to a different page, or to an intercept page. But we can't redirect to an external site.

public class RedirectToExternalException extends AbstractRestartResponseException
{
private static final long serialVersionUID = 1L;

public RedirectToExternalException(String url)
{
RequestCycle rc = RequestCycle.get();
if (rc == null)

{ throw new IllegalStateException( "This exception can only be thrown from within request processing cycle"); }

else
{
Response r = rc.getResponse();
if (!(r instanceof WebResponse))

{ throw new IllegalStateException( "This exception can only be thrown when wicket is processing an http request"); }

// abort any further response processing
rc.setRequestTarget(new RedirectRequestTarget(url));
}
}
}
