Hi all, I was planning to use a refresh pattern in squid 3.5 as follows: refresh_pattern -i .(css|js)\?$ 1440 75% 40320 override-expire override-lastmod reload-into-ims ignore-no-cache ignore-private ignore-must-revalidate That is cache any CSS or JS file that ends with "?" with ignoring the must revalidate flag. However, I see that in Squid 4's documents: http://www.squid-cache.org/Doc/config/refresh_pattern/ Removed ignore-must-revalidate. Other more HTTP compliant directives can be used to prevent objects from caching. What are the options in Squid 4 to achieve the behavior of ignore-must-revalidate? -Skip _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
