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.

Server Configuration


Please see the Overview for the server-level requirements before attempting to use LSCache.

Extension Installation

  1. Clone the Github repo
    git clone
  2. Copy the contents of cscart/* to your CSCart installation
    rsync -a full-page-cache-addon/cscart/ /your/cscart/installation/
  3. Append the contents of htaccess_lscache to your .htaccess
    cat full-page-cache-addon/htaccess_lscache >> /your/cscart/installation/.htaccess
  4. From the CS-Cart admin panel, navigate to Add-ons > Manage add-ons
    !Manage add-ons
  5. Scroll down to Full-page cache add-on and click the Install button.
    !Install full-page cache
  6. Scroll down to Full-page cache add-on again, click the Disabled drop down, and change it to Active.
    !Activate full-page cache

Verify Your Site is Being Cached

You can verify a page is being served from LSCache through the following steps:

  1. From a non-logged-in browser, open the developer tools and navigate to your site. Open the Network tab.
  2. Refresh the page.
  3. Click the first resource. This should be an HTML file. For example, if your page is, your first resource should either be something like or webapp/.
  4. If you see headings similar to
    X-LiteSpeed-Cache: miss
    (for example), this means the page had not yet been cached, but that LiteSpeed has now stored it for future use.
  5. Reload the page and you should see X-LiteSpeed-Cache: hit in the response header. This means the page is being served by LSCache and is configured correctly.
  6. If you don't see X-LiteSpeed-Cache: hit or X-LiteSpeed-Cache: miss, then there is a problem with the LSCache configuration.
