AuthenticationInfoPostProcess redirect failing

I am working with AEM 6.5, backed by Sling for SAML authentication and am having issues with the postProcess method that is invoked after a user is authenticated. I am attempting to do a redirect, but for some reason that is not working, here is what i have in my postProcessor

httpServletResponse.setStatus(HttpServletResponse.SC_TEMPORARY_REDIRECT);

httpServletResponse.setHeader("Location", "https://www.google.com");

I have also tried

try {
    httpServletResponse.sendRedirect("https://www.google.com");
} catch (IOException e)

which is also not working.

Wondering why it seems that sling is blocking the redirect as the client is not being redirected.
