There is - may be some misconfiguration in my squid.conf. If I set max-age to values from interval <1;60> only 302 and 307 redirects were cached (HIT) and no 301. When I increased the max-age value to 61 then the 301 redirect was cached too. But you are right, that the cause of no-caching the 301 redirect is the min value of: refresh_pattern . 0 20% 4320 But for redirects 302 and 307 the above-mentioned refresh_pattern is ignored. My source server is Apache and the corresponding configuration is: RewriteRule /img301.jpg /img.svg [R=301,L,E=rcache:1] RewriteRule /img302.jpg /img.svg [R=302,L,E=rcache:1] RewriteRule /img307.jpg /img.svg [R=307,L,E=rcache:1] Header always set Cache-Control "max-age=3" env=rcache zigi On Thu, Sep 21, 2017 at 2:24 PM, Amos Jeffries <squ...@treenet.co.nz> wrote: > On 21/09/17 22:16, kAja Ziegler wrote: > >> Thats what the "must-revalidate" means.
