save above code as litespeed_cache.xml, and using
vBulletin Admin Control Panel(/admincp)->
Plugins & Products->
Add/Import Product
to import above .xml.

2.rewrite rule in vBulletin's home directory .htaccess
#VBSEO -- original vbseo rules
....
RewriteRule ^(.+)$ vbseo.php [L,QSA]
===>
RewriteRule ^(.+)$ vbseo.php [QSA]

#rules for litespeed cache:
RewriteCond %{HTTP_COOKIE} !vbseo_loggedin=yes
RewriteCond %{HTTP_COOKIE} !bb_userid=
RewriteCond %{HTTP_COOKIE} !bb_password=
#RewriteCond %{ORG_REQ_URI} ^/(index\.php|)$
RewriteCond %{REQUEST_METHOD} ^HEAD|GET$
RewriteCond %{QUERY_STRING} ^$
RewriteRule (.*) - [L,E=Cache-Control:max-age=60]

note:
1. in fact nothing new here, just put all pieces together to make it simple
2. the vBulletin plugin is based on the vB plugin for varnish as we always mentioned in past posts/blog.
Boosting vBulletin Performance with Advanced Caching,the attached file product-boostv1.xml

bit confusing for me , i created and installed plugin as mentioned, but struck at .htaccess i presently have this what should be there instead of it :-

# Comment the following line (add '#' at the beginning)
# to disable mod_rewrite functions.
# Please note: you still need to disable the hack in
# the vBSEO control panel to stop url rewrites.
RewriteEngine On

# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root vB folder (i.e. RewriteBase /forums/)
#RewriteBase /


RewriteCond %{HTTP_HOST} ^mysite.org$ [OR]
RewriteCond %{HTTP_HOST} ^www.mysite.org$
RewriteRule ^/?$ "http\:\/\/www\.mysite\.org\/index\.php" [R=301,L]


RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron|vbseo_sitemap)
RewriteRule ^((archive/)?(.*\.php(/.*)?))$ vbseo.php [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

just quote me what has to be there in that .htaccess file

thanks.

[NiteWave]

the last line of your rewrite rule is
RewriteRule ^(.+)$ vbseo.php [L,QSA]
remove the "L", change to
RewriteRule ^(.+)$ vbseo.php [QSA]

then add those rules follow
#rules for litespeed cache:
in my first post to your .htaccess

[meto]

As I understand we need 2cpu license to support that, correct?

[NiteWave]

yes.
http://www.litespeedtech.com/litespe...-editions.html
see "Disk cache (mod_cache) Support"

[jdeg]

I tried these settings without any luck. Only difference is I'm using 3.8.

[NiteWave]

vB 3.8 should be ok.

to be sure the cookie name is same as previous post:
RewriteCond %{HTTP_COOKIE} !bb_userid=
RewriteCond %{HTTP_COOKIE} !bb_password=

it's customizable by vB admin. for example, if yours is myvb_userid, change above bb_ to myvb_

Thanks for this concise tutorial - I was able to implement it successfully in my forum.

I do have a question about the htaccess rule updates, specifically, I'm wondering why we remove the 'L' from [L,QSA] - I have a few different rewrite rules that include the vbseo.php file, and I want to make sure that I should remove the 'L' from all of them, including here?

RewriteRule content/([0-9]+)-([^/])+ forum/vbseo.php?vbseourl=content.php&r=$1 [L,R]

I think the 'L' means, 'Last rule - stop processing', which makes sense so that it stops once a match is made, instead of continuing to rewrite if another match is made further down the list of rules.

I don't understand how this bit plays into the caching feature.

Can anyone enlighten me on this part a little?

[NiteWave]

good question - there is a better solution. and we've been just aware that not a long time ago.

I'd publish the new suggested rewrite rules by this chance:

usually there exists such a rewriterule in .htaccess of document root:

RewriteCond %{HTTP_HOST} !^www\.mysite\.org$
RewriteRule ^(.*)$ http://www.mysite.org/$1 [R=301,L]

just insert the new cache related rules after above rules:

#rules for litespeed cache:
RewriteCond %{HTTP_COOKIE} !vbseo_loggedin=yes
RewriteCond %{HTTP_COOKIE} !bb_userid=
RewriteCond %{HTTP_COOKIE} !bb_password=
#RewriteCond %{ORG_REQ_URI} ^/(index\.php|)$
RewriteCond %{REQUEST_METHOD} ^HEAD|GET$
RewriteCond %{QUERY_STRING} ^$
RewriteRule (.*) - [E=Cache-Control:max-age=60]

and leave the rest rewrite rules there without change!
the typical ones are:

RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron|vbseo_sitemap)
RewriteRule ^((archive/)?(.*\.php(/.*)?))$ vbseo.php [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

this make lsws cache function easier to use and less chance to make mistakes.

[ihstiv]

Ok - thanks for the update!

to confirm, the latest approach is to leave the 'L' intact in the rule(s) containing 'vbseo.php' - instead of removing it as recommended previously.

So use this:
RewriteRule ^(.+)$ vbseo.php [L,QSA]

..and not this:
RewriteRule ^(.+)$ vbseo.php [QSA]

correct?
