Thanks for this update Donncha.
I have two questions,
What happens when a comment is posted after ticking the ‘Only refresh the current page when a comment is posted’ option?
Does the cache rebuild take place only for that post and when?
(Few of my best posts, almost receive a comment every minute, so if I understand it correctly, those posts will never be Gzipped?)
Second, what happens when a new post is published after the cache re build? When does the cache build for this ‘new post’?
