Hello,
When using https://wordpress.org/plugins/wp-random-post/ with fastcgi_cache on, on my test site http://ee.leiko.dy.fi/random/ it always returns the same post. This plugin is supposed to give redirect to random post, and ofc works ok without any caching. Any suggestions how to make this work with fastcgi_cache on, or maybe some other plugin that somehow magically works with fastcgi_cache on?
