This directory stores some cache files specific for a given wiki, which means wiki farms should have one such directory per wiki.
It should not be accessible from the web: either you can use the file .htaccess already in this directory, or you should configure it specifically (for example, if your webserver does not recognise .htaccess files).
$wgCacheDirectory is set to false (or not set), the wiki will be slower.
The proposed value is
"$IP/cache". This is commented in the file LocalSettings.php created during the installation and can be de-commented. In this case, you should create the directory
cache in your MediaWiki directory and make it writable by the web server.
Note that you should not set this directory to
'/tmp' else there could be conflicts with other MediaWiki installations on the same server (wiki farms or shared servers).
