vBulletin Guest Cache with LiteSpeed

[dihuta]

Hello,

IBxAnders've just wrote an Blog entry to guide how to use Varnish for Output Caching for vBulletin Guest Pages (ie. index.php and content.php).

URL: vbulletin.com/forum/entry.php?2440-vB4Mance-Part-5-Expert-Level-Boosting-vBulletin-Performance-with-Advanced-Caching

I see LiteSpeed have a powerfuil Output Caching lite Varnish. But I don't know how to do with LiteSpeed. Could you please help to config this.

Doing this will help much vBulletin Forum Owner can decrease high load by using LiteSpeed mod_cache.

Thank you so much.

Hello dihuta, wish you're still monitoring this thread.

We've tried to cache this vBulletin(litespeed support forum) for guest visits for some days and looks successful so far. Just using the way you mentioned in your post: install a vBulletion plugin first, then using litespeed's unique rewrite+cache function to get it done.

It's far more simple and strait-forward than apache + varnish, we'd discuss/help with our users how to implement it under litespeed.

awesome news, get a guide/how to post up for all of us to try so we can provide feedback

Guess next popular apps to test this for would be

1. wordpress
2. drupal
3. openx
4. photopost
5. reviewpost

Thank you so much.

1.install vBulletin plug-in(or "vBulletin Boost Product XML")
product-boostv1.xml‎
please refer the first post in this thread, to get the file's link and download it(currently, it's 657 views)

2.set cache directory
lsws admin console-->Server-->Cache:
Cache Storage Settings->Storage Path:/tmp/diskcache (just for example)

please create this directory in shell:
#mkdir /tmp/diskcache
#chown nobody:nobody /tmp/diskcache
#chmod 700 /tmp/diskcache
(assume litespeed(or lshttpd) process is running as nobody)

3. set vhost's "Cache Policy"
assume vBulletin is natively configured as a lsws vhost "myforum"
lsws admin console->Virtual Hosts->myforum->Cache:

Enable Cache:No
Cache Request with Query String:Yes
Cache Request with Cookie:Yes
Cache Response with Cookie:Yes
Ignore Request Cache-Control:Yes
Ignore Response Cache-Control:Yes

4.use rewriterule to cache php pages which you want to
lsws admin console->Virtual Hosts->myforum->Rewrite:
(assume vBulletin installed in $DOCUMENT_ROOT/forum)

##%## following redirect will reduce cached files:
######## otherwise domain.com/abc.php and www.domain.com/abc.php will create 2 cache files.
RewriteCond %{HTTP_HOST} !^www\.domain\.com$
RewriteRule /forum/(.*)$ http://www.domain.com/forum/$1 [R=301,L]

## select which pages to cache
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} !^/forum/(login|register|usercp|private|profile|cron|image) \.php$
RewriteCond %{REQUEST_URI} !^/forum/admincp
RewriteRule /forum/(.*\.php)?$ - [L,E=Cache-Control:max-age=120]

5. restart litespeed

Note: you may need set a cron job to clean up cace directory /tmp/diskcache. following script is borrowed from $SERVER_ROOT/admin/misc/cleancache.sh:

*/10 * * * * root find /tmp/diskcache -type f -mmin +8 -delete 2>/dev/null

delete cache which created 8 minutes ago(running once every 10 minutes). since we set cache expire time as 120 seconds(2 minutes), so it's safe to delete these cache files.

What if virtualhost is via apache on whm/cpanel based litespeed server ? Would vbseo rewrites interfere with this ?

thanks

rewriterule has no difference. but need put it in httpd.conf, vhost definition section. it's ok to put the rewriterule in .htaccess as well. just need some minor adjustment, since the per server and per directory rewriterule difference.

[dihuta]

I have Litespeed + DirectAdmin. There is no vhost item in Virtual Host list. So where exactly to put these lines? (httpd.conf?)

Enable Cache:No
Cache Request with Query String:Yes
Cache Request with Cookie:Yes
Cache Response with Cookie:Yes
Ignore Request Cache-Control:Yes
Ignore Response Cache-Control:Yes


Thank you.

3. set vhost's "Cache Policy"
assume vBulletin is natively configured as a lsws vhost "myforum"
lsws admin console->Virtual Hosts->myforum->Cache:

For that rewrite url set, how would it be modified to also exclude individual non-vB php pages i.e.


domain.com/about.php
domain.com/contact.php

or exclude wordpress specific pages/directories

domain.com/wordpress
domain/wp-content/

etc ?

dihuta:
please try same settings at server level in your case, then try rewriterule cache, see if it works.

eva2000:
for wordpress, I think wordpress's plug-in: wp super cache(or w3 total cache?) is better, please use it instead. why? since it generate static pages --- that means, if a post has no update, the static page no update too, the static pages won't expire until the post has update. for litespeed cache, as you can see, have to set a expire time, say 120 seconds, or 600 seconds, etc. after it expires, have to re-generate cache again even the original php page has no change at all.
