Using LiteSpeed Cache with Wordpress & WP-Super Cache

[skippybosco]

I am running LiteSpeed Enterprise Edition 4.1.4 and trying to get LiteSpeed Cache setup to work with my Wordpress 3.2.1 and WP Super Cache 0.9.9.9 configuration.

My goal would be that WP Super Cache produces the static files and they are served using LS Cache as suggested by NiteWave in this thread

I'm struggling to figure out the correct .htaccess RewriteRules that I should be using as while I've had some minimal success getting home page cached, I get 404 errors on individual posts as well as not being able to login or access wp-admin.

This is my LS Cache settings:

Storage Path: /diskcache
Max Object Size: 512 KB
Enable Private Cache: Yes
Private Cache Expire Time (seconds): 120
Do-Not-Cache URL: /wp-admin/

This is my existing .htaccess:

# disable directory browsing
Options All -Indexes

# BEGIN WPSuperCache
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
AddDefaultCharset UTF-8
RewriteCond %{REQUEST_URI} !^.*[^/]$

# END WPSuperCache

RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

I've tried adding E=cache-control:max-age=120 to the existing rewrite rules but that does not seem to have any effect.

Thanks in advance for any suggestions / guidance on how to get this working.

LiteSpeed serve static file as fast as serving cached page, actually, cached page is saved as static file.
So, if you make Super Cache work properly, you do not need to worry about page cache. both archive the same goal, the result is similar. And I think Super Cache is better at flushing out-dated pages.

Hey George

yes litespeed web server has inbuilt static file caching already out of the box

Litespeed cache is more for php caching that static file.

@eva2000: to clarify, if I am already serving static files via WP super cache that adding LiteSpeed cache provides no additional value?

LiteSpeed cache may help on pages that are not cached in WP super cache.
I am not sure how many. if most are cached, litespeed cache wont help much.
