Wincache settings for WordPress [notes]
[NOTES]
Specify Wincache object cache in WordPress code.
From http://blogs.iis.net/ruslany/archive...cache-1-1.aspx
and mirrored at http://ruslany.net/2010/03/make-word...-wincache-1-1/
"To configure WordPress to use WinCache user cache API’s copy the following code and put it in the file named object-cache.php located at the /wp-content/ directory of your WordPress site.
Code:
<?php
/*
Name: WinCache Cache
Description: WinCache backend for the WP Object Cache.
Version: 0.1
URI: http://ruslany.net/
Author: Ruslan Yakushev
Install this file to wp-content/object-cache.php
Big thanks to Mark Jaquith (http://markjaquith.wordpress.com/)
whose apc-object-cache.php was used as a basis for this code.
