Question Nginx cache and wordpress

[Nadeem Aslam]

Hi

I've install nginx as reverse proxy to apache using plesk - pretty standard stuff - but i get issue where pages on my wordpress site seem to get cached and until i change the slug it does not appear to update

So there are some wordpress plugins which clear the cache of nginx on save etc

The only thing i can't see in the gui is the location of where the nginx cache would be for a given domain - can someone point me in right direction on how this works out of the box

Thanks
