LSCWP Frequently Asked Questions

Yes, LSCWP will always be free and open source. That said, a LiteSpeed server is required, and there are fees associated with some LiteSpeed server editions (see question 2).

A LiteSpeed server is required in order to use this plugin.

1. LiteSPeed Web Server Enterprise with LSCache Module (v5.0.10+)
2. OpenLiteSpeed (v1.4.17+)
3. LiteSpeed WebADC (v2.0+)

Any single server or cluster including a LiteSpeed server will work.

The cache entries are stored at the LiteSpeed server level. The simplest solution is to use LiteSpeed WebADC, as the cache entries will be stored at that level.

If using another load balancer, the cache entries will only be stored at the backend nodes, not at the load balancer.

The purges will also not be synchronized across the nodes, so this is not recommended.

If a customized solution is required, please contact LiteSpeed Technologies at info@litespeedtech.com

NOTICE: The rewrite rules created by this plugin must be copied to the Load Balancer.

The actual cached pages are stored and managed by LiteSpeed Servers.

Nothing is stored within the WordPress file structure.

Yes it can work well with OpenLiteSpeed, although some features (such as ESI) may not be supported. Any setting changes that require modifying the .htaccess file will require a server restart.

In short, yes. However, for some woocommerce themes, the cart may not be updated correctly. Please see this blog post for a quick tutorial on how to detect this problem and fix it if necessary.

As of version 1.0.10, you may simply add define('LSCACHE_NO_CACHE', true); sometime before the shutdown hook, and it should be recognized by the cache.

Alternatively, you may use the function xxxLiteSpeed_Cache_Tags::set_noncacheable(); for earlier versions (1.0.7+).

If using the function, make sure to check that the class exists prior to using the function.

Please see this article for more information and to learn what else you can do to integrate your plugin with LSCWP.

If you want to optimize your images, we recommend use Image-Optimization function from LSCache.

Use

<div id="postviews_lscwp"></div>

to replace

<?php if(function_exists('the_views')) { the_views(); } ?>

NOTE: The id can be changed, but the div id and the ajax function must match.

Replace the ajax query in wp-content/plugins/wp-postviews/postviews-cache.js with

jQuery.ajax({ type:"GET", url:viewsCacheL10n.admin_ajax_url,
     data:"postviews_id="+viewsCacheL10n.post_id+"&action=postviews",
     cache:!1, success:function(data) { 
     if(data) { jQuery('#postviews_lscwp').html(data+' views'); } } });

Purge the cache to use the updated pages.

The crawler is disabled by default, and must be enabled by the server admin first.

Once the crawler is enabled on the server side, navigate to LiteSpeed Cache > Crawler and set Activation to Enable.

For more detailed information about crawler setup, please see our blog post.
