How to set Redis (page) cache permanent?

Default is TTL of 4 hours, I think. How do i make it permanent, so that only when refreshed the cache is purged?

anyone?

I am also interested in this - is it possible?

I’ve been experimenting. In /etc/nginx/common/redis.conf I changed this line redis2_query expire $key 14400; to 28800. This should double the ttl from 4 hours to 8 hours. I assume this change will be overwritten on an update to easyengine but I’m trying to see what effect this has on the caching.
