Hm, we should definitely support the @path and @rootPathFromName attributes for registerWebInterface, too, maybe it's also possible to move the related code to vibe.web.common in the process. I've opened an enhancement request: #1036

Currently the way to specify a prefix is using WebInterfaceSettings: 

auto s = new WebInterfaceSettings;
s.urlPrefix = "/web/v1";
router.registerWebInterface(new MyWebInterface, s);

Thanks, I misidentified urlPrefix as not working but I had a couple of other things wrong. It does indeed work.
