vBulletin Guest Cache with LiteSpeed

[track1]

I'm testing this feature in a real environment (high traffic vb3 forum), and seems to work well. The level of load on the servers is similar to apache/no-cache but supports many more simultaneous requests without overloading, tested with AB.

For now, I found some problems with 503 errors (not cache related) that are already solved, and at peak times, for some unknown reason, there was an overload of the database server that had not happened before, so I had to go back to apache.

Continue testing, I have 3 active trial licenses will buy if it goes well.

it's rather strange. the cache should reduce php/mysql load a lot.

I have made more intensive tests with litespeed and adding some tuning work as stable as Apache and allow more connections. Finally bought 3 enterprise licenses.

One problem with cache system/vbulletin:
- Cache system works ok, but sometimes store pages of logged-in users and displays to guest users.

My .htaccess is as follows, checking everything (cookie values, etc) is correct, i don't know how that can happen sometimes.

RewriteEngine on
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 %{REQUEST_URI} !^/forum/(login|register|usercp|private|profile|cron|image)\.php$
RewriteRule (.*) - [L,E=Cache-Control:max-age=120]

[NiteWave]

maybe this line
RewriteCond %{REQUEST_URI} !^/forum/(login|register|usercp|private|profile|cron|image) \.php$
not correct for your site?

what's the forum homepage? domain.com/ or domain.com/forum/?

p.s. what's status of the special mysql issue you mentioned last time?

[track1]

that line and path is correct on site .htaccess (some disallowed php files to be cached rule).

Reported logged in-cached pages are sometimes for showthread.php?t=xxxxx

mysql issue was probably some puntual overload, it has not happened again. Everything is working very stable and fast.

this plugin have any usage with litespeed?

// Do not cache logged in user pages
if ( $vbulletin->userinfo['userid'] )
{
        header('X-Accel-Expires: 0');
};

[webizen]

Is this plugin used in every page (php request)? If not, then it can not be used as lsws needs a signature for (non)cacheable page.

with LSWS 4.0.20, change header() code or add a new one

header('X-LiteSpeed-Cache-Control: no-cache' );

it will prevent LSWS from caching this page.
