[Plugin: W3 Total Cache] No enhanced disk option for page cache

Hi

I’ve only just realised I should be using Disk Enhanced for my Page Cache, rather than APC. But, the option is not available – just Disk Basic. Why is it missing please?

My setup:

– Litespeed
– W3TC
– all caches set to APC at the moment
– Amaazon Cloudfront CDN mirror

Also, is there anyway to use litespeed cache with W3TC, or is support in the pipeline like you’ve added Varnish Support? Or, do I just need to add/edit these rewrite rules (http://www.litespeedtech.com/support/forum/showthread.php?t=4719) to get Litespeed to respect W3TC settings:

RewriteEngine On
## cache should be available for HEAD or GET requests

RewriteCond %{REQUEST_METHOD} ^HEAD|GET$
## select which pages to cache
RewriteCond %{HTTP_COOKIE} page_contain_cachetoken=yes
# with other condition

RewriteCond %{QUERY_STRING} !s=[a-fA-F0-9]{32}

# excluding certain URLs
RewriteCond %{REQUEST_URI} !/(login|register|usercp|private|profile|cron|image) \.php$

# cache for 2 mins for php pages only
RewriteRule /(.*\.php)?$ – [L,E=Cache-Control:max-age=120]

# for those not met above condition, enable private cache.
RewriteCond %{REQUEST_METHOD} ^HEAD|GET$
## select which pages to serve from private cache
RewriteCond %{HTTP_COOKIE} !page_contain_cachetoken=yes
# with other condition

RewriteCond %{QUERY_STRING} !s=[a-fA-F0-9]{32}

# excluding certain URLs
RewriteCond %{REQUEST_URI} !/(login|register|usercp|private|profile|cron|image) \.php$

# private cache for however long set in cache policy for php pages only
RewriteRule /(.*\.php)?$ – [L,E=Cache-Control:private]

Thanks in advance for any help
