Tapestry eventually calls ServletResponse.sendRedirect, which is
always a 302. If you want to send a 301 you have to do it manually.
Here's some code that works in the same way as HttpError.
public class PermanentRedirect {
private Link link;
public PermanentRedirect(Link link) {
this.link = link;
}
public Link getLink() {
return link;
}
}
// in AppModule
public void contributeComponentEventResultProcessor(
final Response response,
MappedConfiguration<Class, ComponentEventResultProcessor>
configuration
) {
configuration.add(PermanentRedirect.class, new
ComponentEventResultProcessor<PermanentRedirect>() {
public void processResultValue(PermanentRedirect value)
throws IOException {
response.setHeader("Location", value.getLink().toAbsoluteURI());
// Send error commits the response
response.sendError(301, "Moved Permanently");
}
});
}
