Hi Poul-Henning Thank you for your reply. I know it is TTL+grace. The questions is if grace is much longer than TTL, does it mean varnish will keep multiple expired copies of the same objected instead of the most recent one? In case an old object needs to be used (for example, saintmode), which expired copy will be used? Will it be the most recent one?
I am asking this because I want to set grace longer so I can show the end-user something in case of backend server error. However, I am worried that: 1) a long grace will fill up the memory (will it?) 2) older objects will be used even if there are newer (but expired) objects available. (how expired objects are used?)
