I want to test WinCache on XAMPP, but I can't.
I copied php_wincache.dll file into the PHP extensions folder. Then I added the correct code to the php.ini file.
Next, when I tried to restart Apache, there was a pop-up dialog showing following error message:
php5.dll is missing
(not the exact sentence, I translated from the original Chinese message)
Though the WinCache official said wincache can only work on IIS, in fact, someone mentioned that wincache can also work on Apache.
So, I hope you can add this caching method into XAMPP.
