Here's a good function header given the following:
I wrote the below code

    def decorator(func):
        @wraps(func)
        def inner(request, *args, **kwargs):
            def get_last_modified():
                if last_modified_func:
                    dt = last_modified_func(request, *args, **kwargs)
                    if dt:
                        return timegm(dt.utctimetuple())
            res_etag = (etag_func(request, *args, **kwargs) if etag_func else None)
            res_etag = (quote_etag(res_etag) if (res_etag is not None) else None)
            res_last_modified = get_last_modified()
            response = get_conditional_response(request, etag=res_etag, last_modified=res_last_modified)
            if (response is None):
                response = func(request, *args, **kwargs)
            if (request.method in ('GET', 'HEAD')):
                if (res_last_modified and (not response.has_header('Last-Modified'))):
                    response['Last-Modified'] = http_date(res_last_modified)
                if (res_etag and (not response.has_header('ETag'))):
                    response['ETag'] = res_etag
            return response
        return inner
    return decorator

What's a good function header?
