You were right. After I added header Cache-Control "max-age=60, must-revalidate" to the redirects, then the response was cached. Thank you for clarification. 301 should be cached unless the object would need revalidation immediately. But for 301 I always get MISS - with and without a cache-control header: $ curl -v http:/test.example.com/img301.jpg > GET /img301.jpg HTTP/1.1 > Host: test.example.com > User-Agent: curl/7.50.1 > Accept: */* > < HTTP/1.1 301 Moved Permanently < Date: Thu, 21 Sep 2017 06:44:41 GMT < Server: Apache < Cache-Control: max-age=60, must-revalidate < Location: http://test.example.com/img.svg < Content-Length: 247 < Content-Type: text/html; charset=iso-8859-1 < X-Cache: MISS from <squid-proxy> < X-Cache-Lookup: MISS from <squid-proxy>:3128 I can't find any information on Squid wiki or via Google if the object need revalidation immediately. I use Squid 3.4.14 from CentOS 6 package squid34-3.4.14-15.el6.x86_64.
