LiteSpeed Support Forums - Can't Get vBulletin Cache Working

I've been trying to get the vBulletin/Litespeed cache working today with no success.

Site is forum.rpg.net.

I generally followed the instructions here:
http://blog.litespeedtech.com/2011/0...uilt-in-cache/

I installed product-boostv1.xml with changes per here:
http://vbtechsupport.com/127/

I created the cache directory and put that info into Settings->Storage Path:. Later, just to make sure all was well, I turned on caching generally and saw things got written here. So, this seems to be right. (General caching was turned back off afterward.)

I have imported apache vHosts, so I didn't set any policy.

I added info to the existing .htaccess:

PHP Code:

RewriteCond %{HTTP_COOKIE} !bbimloggedin=yes RewriteCond %{HTTP_COOKIE} !bbuserid= RewriteCond %{HTTP_COOKIE} !bbpassword= RewriteCond %{REQUEST_METHOD} ^HEAD|GET$ RewriteCond %{QUERY_STRING} !s=[a-fA-F0-9]{32} RewriteCond %{QUERY_STRING} !product=vbnexus RewriteCond %{REQUEST_URI} !^/admincp RewriteCond %{REQUEST_URI} !^/(login|register|usercp|private|profile|cron|image)\.php$ RewriteRule (.*\.php) - [L,E=Cache-Control:max-age=120]

(PS: A bug in the original post puts a space " " before the \.php in the above.)

I've restarted the Litespeed server many times by this point.

I logged in and verified that the bb_imloggedin is getting set. The only oddity is that it's a cookie set on rpg.net rather than forum.rpg.net, because I share vB cookies with the rest of the site.

But, no caching occurs from vBulletin:
