Yes, but CSS to a static file and Defer JS will work for every user guest/member.So caching only works for guests, right?
Yes, unless you don't enable caching on last page of the thread on admin options.What does caching mean? That when I do "reload page" as a guest, I won't see new messages, updates of the page? Just when 600 seconds are over and the site is cached again, then I will see those updates?
Then its' automatically updated with new post.
