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.

Package Installation


Please see the Overview for the server-level requirements before attempting to install this package.

Require this package using composer.

composer require litespeed/lscache-laravel

Laravel uses Auto-Discovery, so you won't have to make any changes to your application, the two middlewares and facade will be available right from the beginning.

Steps for Laravel >=5.1 and <=5.4

The package can be used for Laravel 5.1 to 5.4 as well, however due to lack of Auto-Discovery, a few additional steps have to be performed.

In config/app.php you have to add the following code in your aliases:

'aliases' => [
    'LSCache'   => Litespeed\LSCache\LSCache::class,

In app/Http/Kernel.php you have to add the two middlewares under middleware and routeMiddleware:

protected $middleware = [

protected $routeMiddleware = [
    'lscache' => \Litespeed\LSCache\LSCacheMiddleware::class,
    'lstags' => \Litespeed\LSCache\LSTagsMiddleware::class,

Copy lscache.php to config/:

Copy the package config/lscache.php file to your config/ directory.


Do not add the ServiceProvider under providers in config/app.php.

Steps for Laravel 5.5 and above

You should publish the package configuration, which allows you to set the defaults for the X-LiteSpeed-Cache-Control header:

php artisan vendor:publish --provider="Litespeed\LSCache\LSCacheServiceProvider"

Enable CacheLookup for LiteSpeed Cache

To enable CacheLookup for LiteSpeed Cache, you have to include the following code, either on server, vhost or .htaccess level:

<IfModule LiteSpeed>
   CacheLookup on

Verify Your Site is Being Cached

!Verify Cache Miss

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

  1. From a non-logged-in browser, navigate to your site, and open the developer tools (usually, right-click > Inspect). 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. You should see headings similar to these:
    X-LiteSpeed-Cache: miss
    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.
  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.
    !Verify Cache Hit

Alternative Headers

The 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 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.
