Introduction<\/h2>\n

LiteSpeed Cache plugins are available for a variety of web applications, including WordPress, Joomla!, and Drupal. But do you know why you should cache your apps? Or why a LiteSpeed Cache plugin is uniquely capable of delivering your web content quickly and accurately?<\/p>\n

Let\u2019s talk about all of that, and then look at a quick and easy way to see if your website supports LiteSpeed Cache.<\/p>\n

Why Cache Your Web App?<\/h2>\n

Let\u2019s start with a basic explanation of what a cache is. Generally speaking, a cache is a way of storing data so that it is easier or faster to retrieve than the original source.<\/p>\n

With many web applications, caches are particularly helpful. The dynamic pages generated by these apps don\u2019t exist anywhere in the file system. They are built on demand with PHP or some other method. So even though the web app\u2019s pages are served to the visitor as HTML, generating<\/em> them can be resource-intensive. And slow.<\/p>\n

This is where LiteSpeed Cache comes in. LiteSpeed takes the dynamically generated web page, and stores it as a static HTML snapshot. That way, the next time the page is requested by a visitor, the snapshot can be served immediately. Serving a snapshot is much faster and uses far fewer resources than generating the page dynamically does.<\/p>\n

Why Use a LiteSpeed Plugin?<\/h2>\n

If you know a little something about .htaccess<\/code> files, and how to use rewrite rules, you can control the LiteSpeed Cache Engine that way. All it takes is a few rewrite rules<\/a> in your application\u2019s document root .htaccess<\/code>, and you can have a simple page cache.<\/p>\n

So what do you gain by using an LSCache plugin? Quit a lot actually.<\/p>\n

An LSCache plugin bridges the knowledge gap between a web app and the Cache Engine.<\/strong><\/p>\n

Let\u2019s put it another way: web applications have rules about what content you can cache, and when that cache should expire or be purged. An LSCache plugin understands these rules, and instructs the server Cache Engine how to proceed. This communication is not something that you can duplicate with rewrite rules.<\/p>\n

For example, let\u2019s say you have a WordPress site. The LSCache plugin for WordPress knows that when a post is edited, saved, or deleted, that post must then be purged from the cache. But it goes even further than that.<\/p>\n

The LiteSpeed Cache engine is equipped with a handy tagging system that allows cached pages to be grouped together and purged all at the same time. This purge tag functionality is very powerful. It means that LSCache can do a targeted purge, removing the edited page, as well as every other page that is influenced by it. Without a tagging system, other plugins may either purge too little (just the single page) or too much (all<\/em> of the site\u2019s pages).<\/p>\n

So, returning to our WordPress example, when the plugin knows to purge an edited post from the cache, it also knows to purge everything else that shares the same purge tags as that post. That can include the category pages for the post\u2019s categories, monthly archives for the post\u2019s publication date, author archives for the post\u2019s author, and more.<\/p>\n
