How set X-Accel-Expires in add_view, add_static_view

Hello

I want use cache nginx and cache browser.

For managing cache nginx i use X-Accel-Expires.
For managing cache browser i use Cache-Control.

Cache-Control is simple, need set parameters http_cache in add_view and
cache_max_age in add_static_view.

But how set X-Accel-Expires in same level?(as a parameter in add_view)

In my opinion such parameter does not exists or am I mistaken?
if so, how to pass this parameter to "tween"?
So I installed it there:

config.add_view(
cache_view,
route_name='cache_view',
renderer='test_cache_nginx:templates/index.jinja2',
http_cache=10,
* x_accel_expires=100*,

#tween:
def simple_tween_factory(handler, registry):

def simple_tween(request):

response = handler(request)
#*x_accel_expires* = ... here i get parameter ...

if not *x_accel_expires*:
x_accel_expires =
registry.settings.get('cache.x_accel_expires', 0)
response.headers.add('X-Accel-Expires', x_accel_expires)

return response

return simple_tween
