Litespeed Cache Headers

[Ax2music]

We have just migrated from Apache to Litespeed and we are seeing a huge speed improvement of our websites already but we want to migrate to also having Litespeed cache. The problem is I've edited our WHM settings as below, but I'm always getting the header response of no-cache as shown below. What am I missing?
CacheRoot /tmp/ramdisk CacheLookup on RewriteEngine On RewriteCond %{REQUEST_URI} !/admin/ [NC] RewriteRule .* - [E=cache-control:max-age=120]
<FilesMatch ".(css|ico|flv|gif|jpeg|jpg|js|pdf|png|swf|text|html|text/html)$"> Header append Cache-Control "no-store, no-cache, must-revalidate" Header edit Cache-Control "^[, ]*$" "max-age=1800, public"
Website Header Response
Access-Control-Allow-Origin: * Cache-Control: no-store, no-cache, must-revalidate Content-Encoding: br Content-Length: 27281 Content-Type: text/html; charset=UTF-8 Date: Wed, 21 Feb 2024 21:17:21 GMT Expires: Thu, 19 Nov 1981 08:52:00 GMT Pragma: no-cache Server: LiteSpeed

X-Xfpc-Cache: Hit

first: disable xFPC mod. xFPC use same technic to store page in static html file

but LSCache is native technic of LiteSpeed.

<FilesMatch ".(css|ico|flv|gif|jpeg|jpg|js|pdf|png|swf|text|html|text/html)$"> Header append Cache-Control "no-store, no-cache, must-revalidate" Header edit Cache-Control "^[, ]*$" "max-age=1800, public"

in my opinion - these lines must be removed

CacheRoot /tmp/ramdisk CacheLookup on RewriteEngine On RewriteCond %{REQUEST_URI} !/admin/ [NC] RewriteRule .* - [E=cache-control:max-age=120]

must be:

RewriteEngine On
<IfModule LiteSpeed>
CacheRoot /tmp/ramdisk
CacheLookup on
RewriteCond %{REQUEST_URI} !/admin/ [NC]
RewriteRule .* - [E=cache-control:pubic,max-age=86400]
</IfModule>

1800 - 30 mins for public cache???????

 

[Ax2music]

Disabled xFPC.

Removed the lines, and copy and pasted your code, and restarted litespeed service. We were starting low on the cache just to confirm a few things it will planned to increased to 1 day, as you did.
Here is the latest info, Also I'm seeing errors on the litespeed config page.

Thank you! I just was looking at these when I started googling them. Doesn't seem like it is a huge deal, taking care of that now. But should not prevent cache from working I don't think?

I am also trying to figure out the expires issue and resolve that.

Where did you add this configuration in WHM? WHM is a server control panel for server wide configuration, so if you want to configure the configuration of a domain use root .htaccess in document_root.

It is being added under Apache> Include editor > Pre Main Include. If I do it in .htaccess WHM will overwrite any changes at restart of the service. I can view the .htaccess file and the additions are in there.

 

[serpent_driver]

Remove it. It is better to configure such settings per domain and not server wide. Come back if done. I will teach you to configure the right settings for cache and everything else.

We us MODX

 

[serpent_driver]

There is no LScache plugin for MODX (yet). You don't necessarily need an LScache plugin because you can also configure LScache via .htaccess, but if you have little to no knowledge of it, then it's simply impossible to instruct you to use LScache together with MODX.

I recommend you use a CMS for which there is an LScache plugin. If switching to another CMS is not an option for you, then you need a LiteSpeed expert to configure LScache for you using .htaccess.

Thank you, we are already working on just paying support to help set it up. Changing CMS is not an option.

Get in touch if you need help. If someone doesn't know LiteSpeed and LScache, you'll pay a lot of money to learn LiteSpeed.

[AndreyPopov]

then you need a LiteSpeed expert to configure LScache for you using .htaccess.

if:
- not use different views for desktop, tablet and mobile devices
- not use different views for logged users and guests
- not use webp/avif/apng images on some devices and jpg/png on other devices
then configure LScache by .htaccess is easy.


in most common situations

RewriteEngine On
<IfModule LiteSpeed>
CacheRoot /path_to_store_cache
CacheLookup on
RewriteCond %{REQUEST_URI} !/admin/ [NC]
RewriteRule .* - [E=cache-control:max-age=86400]
</IfModule>

is enough

This a is very general information, but it cannot be used universally because this information depends very much on which CMS you use. It is therefore not recommended to use your tips.

RewriteEngine On <IfModule LiteSpeed> CacheRoot /path_to_store_cache CacheLookup on</IfModule>

This is not a must and it is better to control cache location in LiteSpeed WebAdmin.

Please don't give any advices for LSWS. You don't have it! This also means for LSWS WebAdmin you also don't have!
