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 Content-Type: text/html; charset=ISO-8859-1 Date: Wed, 07 May 2008 14:47:00 GMT Server: gws X-Cache: MISS from localhost.localdomain Via: 1.0 localhost.localdomain:3128 (squid/2.7.DEVEL0-20080506) Connection: close more access.log 1210171620.299 75 192.168.75.133 TCP_MISS/404 7682 GET http://www.google.com/idontexist - DIRECT/72.14.253.104 text/html 1210171629.695 63 192.168.75.133 TCP_MISS/404 7682 GET http://www.google.com/idontexist - DIRECT/72.14.253.104 text/html Bug?
