Re: Graceful handling of ajax after session expiration

Thanks for the response! I'm not sure if this solves my problem though, or if I understand this correctly. Even if I use HybridUrlCodingStrategy to mount the page, I will still get redirected to a Session Expired page if I try to use any ajax-enabled component.
