Do you get an error, or is your header just ignored?

Are you sure it's not because the response has already been committed?
That's the usual problem. Are you attempting to add your header before
or after the response body is generated?

Note that a 304 response usually does not have much in the way of a
response body, and so the response may not have been committed.

I think you need to set your header earlier in the request/response time
line.
