+Subject: [PATCH] support http header to indicate an expected failure
+
+By setting an extra HTTP header 'X-Pacman-Expected-Failure' the server can
+indicate that the failure is expected. The next server is tried without
+error message and without increasing the server's error count.
+
+This can be used by servers that are not expected to be complete, for
+example when serving a local cache.
