nginx-headers-more and If-Unmodified-Since

Hi,

I'm using nginx-headers-more to set a fixed last-modified header on the 
responses of my server.
The problem I'm having is that when a request comes in with 
'If-Unmodified-Since' nginx's ngx_http_not_modified_filter runs before 
headers more,
and therefore sees no last-modified header in headers_out and fails the 
request with HTTP 412.

Correct.

Right.

Sadly no.
