Hi all, I've been reading the past posts about header_replace but can't seem to get an answer. I run squid in cache acceleration mode, I'm trying to return a specific expiration date in the header for the images I cache from my backend servers. As far as I Know I tried setting the value "header_replace Cache-Control max-age=10080" in the squid.conf file but I still get a random expiration date. I also tried setting "header_access Cache-Control deny all" and set "refresh_pattern . 10018 0% 10080". What do I need to do exactly for squid to respond to the client's web browser with a specific expiration date in the header? Thanks all, Jon
