Probably it works in this case because browser just shows to you cached page,
that was retrieved earlier over http or https.

There's no difference between SPDY and HTTP/HTTPS. In debug logs, that
you have provided, the client didn't send "If-none-Match" and it's normal.

Anyway, missing or presence "If-none-Match" header shouldn't result in
empty responses from your backend.
