5 # Tests for not modified filter module and it's interaction with proxy.
6 #
7 # Notably, requests which are proxied should be skipped (that is, if
8 # a backend returned 200, we should pass 200 to a client without any
9 # attempts to handle conditional headers in the request), but responses
10 # from cache should be handled.
