Wordpress LScache Plugin: What is the difference between the LiteSpeed Server vs the LiteSpeed Plugin
Last Updated on: Wed, 15 Apr 2026 00:00:02 Can you please verify a few things concerning the LiteSpeed Server vs LiteSpeed Plugin : https://www.litespeedtech.com/products/litespeed-web-server/control-panel-plugins/download https://blog.cpanel.com/litespeed-web-server-now-supported/ If I install the LiteSpeed plugin to all of my websites, do I NEED the LiteSpeed Server at all ? Does installing the LiteSpeed Server REPLACE the Apache Server altogether? , or is it just an additional function within WHMs interface ? If it is just an additional function to WHM, what are the command lines to install LiteSpeed Server within our VPS ? OR.. what are the exact steps to install it via WHM ? Is there a video tutorial on how to install into WHM ? And are the features from the FREE installation trial only ? In other words, will the features of the LiteSpeed server disappear or stop working at some point ? =============== Thanks in advance. This topic was modified 3 years, 11 months ago by Pigo3934blog.

This might answer your question: The LSCache Module is built into your licensed copy of LiteSpeed Web Server. When it comes to caching dynamic content, the LSCache Module does all of the work. The LSCache Plugin for WordPress is simply an interface. It allows WordPress to instruct the server Module on what to cache, how long to cache it, and when to purge. And it allows the site owner to manage and configure the Module. Without the Module, the Plugin could not function. A licensed LSCache Module is required in order to use the free LSCache Plugin. Now, the WHM plugin you linked to is something entirely different, and is outside of the scope of this forum. You might want to join our Slack community to discuss it. Youll find a lot of knowledgeable people there who use it every day. If you install LiteSpeed Web Server it does replace Apache. There are a few flavors of free. There is the free trial, which entitles you to test drive a Web Host level license in your own environment, but it does expire after 15 days. Additionally, there is the Starter License, which is free forever, and will not disappear or stop working. You can compare the available licenses here. I hope this clears it up a bit. If you have more questions about all of this, please drop by Slack. Thanks! Thank you for the quick reply. So basically, we can either work from our Host Server, or just use the plugin on individual websites ? 1) ? No difference whether administrated on the host server or via the plugin? Both ways have the same functionality, correct ? 2) ? Are we missing any functionality if we do not have the LSCache module on the server ? 3) ? How do we install the LSCache onto the server ? 4) ? Can we still keep Apache and use the LSCache module too ? 5) ? Do we even need the LSCache module if we are using the WP plugin ? ========= Look forward to your reply. Thanks in advance. Reason: Added more questions 1. Im not sure what you mean by this question. Can you clarify, please? 2. Yes. The LSCache plugin has two sets of features: general optimization features that can be used by anyone with any web server, and exclusive features that can only be used with a LiteSpeed Web Server. You can see those features listed on the directory page. 3. If you purchase a license for LiteSpeed Web Server, the LSCache module is automatically included in your license. Our wiki includes instructions for setting up LiteSpeed Web Server, including LSCache setup. 4. No, the LSCache module is unique to LiteSpeed Web Server. 5. It depends. If you want to use the exclusive caching features, then yes, you do need LiteSpeed Web Server with the LSCache module. Otherwise, you can still use the general features without the module, as described in Question 2. I hope this helps!
