[Plugin: W3 Total Cache] How to choose directory for disk caching

An easy way to change the directory is to create a link from the pgcache directory to where you want the pgcache to be.

For example, I moved the pgcache to be stored in-memory with these commands:

cd /var/www/html/wp-content/w3tc
sudo rm -rf pgcache
sudo ln -s /dev/shm/pgcache pgcache
sudo chown apache:apache pgcache

(paths with vary on your system)

The link looks like this:

$ ls -l /var/www/html/wp-content/w3tc/pgcache
lrwxrwxrwx 1 apache apache 16 Jul 29 21:13 /var/www/html/wp-content/w3tc/pgcache -> /dev/shm/pgcache
