-Subject: [PATCH 1/1] support http header 'Cache-Control: no-cache' for soft
- failure
-
-The idea has been borrowed from cloud providers' reverse proxies and
-load balancers. These accept http headers to control caching behaviour,
-even to control 'negative caching' when error codes are returned.
-
-By setting the http header 'Cache-Control: no-cache' when returning with
-the status code 404 (not found) the server can indicate that this is a
-soft failure. No error message is shown, and server's error count is
-not increased.
-
-This can be used by servers that are not expected to be complete, for
-example when serving a local cache [0]. In nginx this can be achived by
-acting on error_page and sending the extra header by adding a directive:
-
-    server {
-        listen 8080 default_server;
-        root /var/cache/pacman/pkg;
-        error_page 404 = @no-cache;
-        location @no-cache {
-            add_header Cache-Control "no-cache" always;
-        }
-    }
-
-Also this is a perfect match for pacredir [1].
