I've seen cache plugins for Varnish and Litespeed Cache, but no luck finding an output caching equivalent for nginx. Basically, we sometimes receive huge viral spikes from forum posts being shared, and Litespeed Cache was a godsend because it allowed us to cache pages to guests (who accounted for most of the viral spike viewers), which gave MySQL a great break, which kept CPU/RAM stable. Is there any such tutorial or plugin for nginx? We'd like to switch, but every post I've found about fastcgi and output caching for nginx seems pretty quiet. Am I better off sticking with Litespeed for now? Thanks!
