Hi there, I am trying to cache 404 responses that have the Cache-Control header set to private by configuring squid to ignore such caching. It seems to work fine for 200 responses, but fails to work on 404 responses.

I adjusted the squid conf the following way:
refresh_pattern 999999 100% 999999 override-expire ignore-reload
override-lastmod ignore-no-cache ignore-private ignore-auth
ignore-stale-while-revalidate.

And then I also tried to remove the Cache-Control Header via the:
header_access Cache-Control deny all

/usr/local/squid/bin/squidclient -p 3128 -h 192.168.75.133 http://www.google.com/idontexist
HTTP/1.0 404 Not Found

Bug? Configuration mistake?
