The relevant code at ControllerServlet:184 is:

    httpRes.addHeader("Cache-Control", "no-cache");


This one is happening in our production environment (running 4.0.s110524). We cannot currently reproduce it in 4.0.19 final, but that might be because it's being masked by the issues I raised earlier.
