Before installing and activating the LSCache plugin, deactivate all other full-page cache plugins.
You can still use other types of cache (like object cache), but only one page cache can be used at a time, so you’ll need to disable any other page caches, if you want to use LSCache.
Please see the Overview for the server-level requirements before attempting to use LSCache.
- Clone the Github repo
git clone https://github.com/litespeedtech/full-page-cache-addon
- Copy the contents of

rsync -a full-page-cache-addon/cscart/ /your/cscart/installation/
- Append the contents of
cat full-page-cache-addon/htaccess_lscache >> /your/cscart/installation/.htaccess
- From the CS-Cart admin panel, navigate to Add-ons > Manage add-ons
- Scroll down to Full-page cache add-on and click the Install button.

Verify Your Site is Being Cached¶
You can verify a page is being served from LSCache through the following steps:
- From a non-logged-in browser, navigate to your site, and open the developer tools (usually, right-click > Inspect). Open the Network tab.
- Refresh the page.
- Click the first resource. This should be an HTML file. For example, if your page is
http://example.com/webapp/, your first resource should either be something like
- You should see headings similar to these: These headings mean the page had not yet been cached, but that LiteSpeed has now stored it, and it will be served from cache with the next request.
X-LiteSpeed-Cache: miss X-LiteSpeed-Cache-Control:public,max-age=1800 X-LiteSpeed-Tag:B1_F,B1_
- Reload the page and you should see
X-LiteSpeed-Cache: hitin the response header. This means the page is being served by LSCache and is configured correctly.
X-LiteSpeed-Cache header is most common, but you may see
X-LSADC-Cache if your site is served by LiteSpeed Web ADC. You may also see
X-QC-Cache if your site was served via QUIC.cloud CDN. These alternate headers are also an indication that LSCache is working properly on your site.
If you don't see
X-LiteSpeed-Cache: hit or
X-LiteSpeed-Cache: miss (or any of the alternative headers), then there is a problem with the LSCache configuration.
