-======LSCWP Frequently Asked Questions======
+====== LiteSpeed Cache for WordPress: FAQs======
+**Please Note**: This wiki is valid for v2.9.x and below of the LiteSpeed Cache Plugin for WordPress. If you are using v3.0 or above, please see [[https://docs.litespeedtech.com/lscache/lscwp/overview/|the new documentation]].
-=====Is the LiteSpeed Cache Plugin for WordPress free?=====
+Here are some of our most Frequently Asked Questions.
+===== Why do the cache features require LiteSpeed Server? =====
-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).
+This plugin communicates with your LiteSpeed Web Server and its built-in page cache (LSCache) to deliver superior performance to your WordPress site. The plugin’s cache features indicate to the server that a page is cacheable and for how long, or they invalidate particular cached pages using tags.
+LSCache is a server-level cache, so it’s faster than PHP-level caches. [[https://www.litespeedtech.com/benchmarks/wordpress|Compare with other PHP-based caches]].
+A page cache allows the server to bypass PHP and database queries altogether. LSCache, in particular, because of its close relationship with the server, can remember things about the cache entries that other plugins cannot, and it can analyze dependencies. It can utilize tags to manage the smart purging of the cache, and it can use vary cookies to serve multiple versions of cached content based on things like mobile vs. desktop, geographic location, and currencies. [[https://blog.litespeedtech.com/tag/caching-101/|See our Caching 101 blog series]].
+If all of that sounds complicated, no need to worry. LSCWP works right out of the box with default settings that are appropriate for most sites. [[litespeed_wiki:cache:lscwp:beginner|See the Beginner’s Guide]].
+**Don't have a LiteSpeed server?** We're beta testing our new QUIC.cloud CDN service, and it allows sites on //any server// (nginx and Apache included) to experience the power of LiteSpeed caching! [[https://quic.cloud|Click here]] to learn more or to give QUIC.cloud a try!
+===== What about the optimization features of LSCache? =====
+LSCWP includes additional optimization features, such as Database Optimization, Minification and Combination of CSS and JS files, HTTP/2 Push, CDN Support, Browser Cache, Object Cache, Lazy Load for Images, and Image Optimization! And now, many of these features do not require the use of a LiteSpeed web server.
+===== Is the LiteSpeed Cache Plugin for WordPress free? =====
+Yes, LSCWP will always be free and open source. That said, a LiteSpeed server is required for the cache features, and there are fees associated with some LiteSpeed server editions.
 =====What server software is required for this plugin?=====
-A LiteSpeed server is required in order to use this plugin.

 Any single server or cluster including a LiteSpeed server will work.
+Many of the optimization features may be used with any web server. LiteSpeed is not required.
+=====What is the difference between the LSCache Module for LSWS (requires a license) and the LSCache Plugin for WordPress (free)?=====
+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.

 =====Are my images optimized?=====
-If you want to optimize your images, we recommend use [[https://www.litespeedtech.com/support/wiki/doku.php/litespeed_wiki:cache:lscwp:image-optimization | Image-Optimize function]]
+Images are not optimized automatically, but if you'd like to have it done we provide an [[litespeed_wiki:cache:lscwp:image-optimization | Image-Optimization]] function. Find it at **LiteSpeed Cache > Image Optimization**.
+===== How do I make a WP nonce cacheable in my third-party plugin? =====
+Our API includes a function that uses ESI to "punch a hole" in a cached page for a nonce. This allows the nonce to be cached for 12 hours, regardless of the TTL of the page it is on. Learn more on [[litespeed_wiki:cache:lscwp:api#nonce_issues|our API wiki]].

+===== Why are some settings tabs missing? =====
+LSCWP has a "Basic View" and an "Advanced View." While in Basic View, you will see the following settings tabs: **General**, **Cache**, **Purge**, **Excludes**, and (optionally) **WooCommerce**. These are all that is necessary to manage the LiteSpeed Cache.
+Click on the ''Advanced View'' link at the top of the page, and several more tabs will be revealed: **Optimize**, **Tuning**, **Media**, **CDN**, **ESI**, **Advanced**, **Debug**, **Crawler**. These tabs contain more expert-level cache options as well as non-cache-related optimization functionality.
