OK, I've now enabled XCache on my PS, and it all appears fine (& working) in phpinfo().
However, if I go the XCache administration pages, only the admin pages appear to be caching and nothing else on my server!
I'm wondering if this might be something to do with needing a particular FastCGI config on each domain. Here's my FastCGI config:
--- DH-PHP handlers ---
AddHandler fastcgi-script fcg fcgi fpl
AddHandler php-fastcgi .php
Action php-fastcgi /cgi-bin/dispatch.fcgi
exec /dh/cgi-system/php5.cgi $*
I'm not sure if anyone else has a similar set-up and has got this working? My domain is using the FastCGI 'PHP mode' (from the DreamHost panel) and has XCache enabled, but nothing seems to be caching for that site (according to the admin stats).
