It turns out that mod_proxy is dropping the 'n' header on its way out. I tried a number of things to make sure it's getting preserved, but it isn't. After that, I tried nginx. On the plus side, nginx *does* preserve the n header on its way out. At the other hand, now all of a sudden Jenkins starts complaining about the reverse proxy not being configured correctly, and apparently there is other stuff that is missing as well with nginx support.
Is anybody using Apache or Nginx with HTTPS in front of Jenkins *at all*?
