krait.config module¶
This module is used to configure the behaviour of Krait when a request arrives and when its response is sent. Currently, this module is used to configure routing and the client-side cache.
The members of this module should only be changed from .py/init.py

routes
= None¶ list of
Route
– The list of routes to be read by Krait. The default is all GETs to default targets, deny anything else. If you override this, the last route should be a default one (Route()

cache_no_store
= []¶ list of str – The list of filename regexes that the clients shouldn’t cache.
-
krait.config.
cache_private

-
krait.config.
cache_long_term
= []¶ list of str – The list of filename regexes that can be kept for a longer time. This duration is configured with
krait.config.cache_max_age_long_term
This is a modifier, so it can be applied to both private or public cache directives.
-
krait.config.
cache_max_age_default
= 300¶ int – The number of seconds that clients should not re-request the resource. This corresponds to the Max-Age of the HTTP response, for public or private (and not long-term) cached resources.
