Hi, I already try this... but... not work =/
when in the page, I do "shift+f5", page is re-read "EXPIRED"... OK
but, this entering in the page, or do F5 ... page = HIT cache...
In this specifics pages, I always put php header "cache-control, pragma, etc" as "no-cache", so, I want always get a new page from backend... understand?
