thanx donncha for your reply..
I have changed everything to “recommended setting”.
The documentation says: “Experiment with different values and visit this page to see how many expired files remain at different times during the day.”
May I know what will probably be the best number of “expired files” for my blog with 800 posts and 4500 page views per day?
Sorry for such questions. Am not a techie guy..
Thanks in advance..
