Hyper Cache Version 2.5.9
I’ve made a number of minor releases until today just to try to solve a “date” bug that was affecting the cache system of some browser (Chrome and Safari for sure).
I was a my fault when I rewrote partially the plugin to make it easy to install.
The latest update, I hope, will solve any problems. If there is no other bugs, I want to have a rest time over Hyper Cache development cause my regular job is making me really busy!
My excuses for my bad english but it's the only way I have to communicate with you. Would you suggest
a correction? Leave a comment, thank you!

great..just a little suggestion. is_file and is_dir is much faster than
file_exists
