Web browsers and how they work is the reason why caching has become a part of our everyday life. If you can't access a site or if you get errors while loading, experts suggest cleaning the cache – it's a standard procedure that helps in most cases.
In our article, we will try to expand our knowledge about caching, delve into specialized documentation, and figure out how to implement this efficient process on your site with the LiteSpeed plugin.
First, let's define the terminology. A cache is a place where temporary data, such as photos, page formatting, or text, is stored. The cache is needed so that when the page is accessed again, the information can be presented to the user faster.
Caching is a mechanism for storing data. The caching process occurs in such a way that cache data can be retrieved more easily or more quickly than data from the original source. This is useful for the site owner for several reasons.
Let's start by examining what happens when a visitor enters any of the pages of the site:
There may be delays or errors at each stage. They are due to the fact that the servers with the necessary elements and information may not respond. And the generation of dynamic pages can be resource-intensive and slow.
This is what caching is for. During this process, copies of items that are frequently requested are created. If the page has been cached, your server or visitors' browsers will provide a static copy of the page.
Caching is suitable for content that does not change over time. You can cache such a page and send it to the user when he opens a certain link.
There are actually several types of caches. LSCache is a "page cache". The task of the page cache is to save a dynamically created page as a static copy of HTML.
Thus, if a visitor revisits the page, a copy will be sent to them immediately. Maintaining a cached page is much faster and requires far fewer resources than dynamically generating elements and data.
Imagine that the pages on your site are not cached. A visitor requests any of those pages, and the following happens:
A few minutes later another visitor requests the same page. The algorithm changes:
Once the page is in the cache, the number of steps between a page request and retrieval is reduced, and the slow performance of the web application is eliminated from the algorithm.
From then on, until the cache object expires, visitors requesting that page won't have to wait for the web application. This is why caching improves visitor interaction with the site and reduces the load on your server.
Despite all the advantages of using the cache, there is one small disadvantage that can cause problems for visitors. It is that the client can view old data.
Because the caching is not properly configured, the browser will not be able to verify the cached content. Consequently, the visitor loads outdated content, which negatively affects the user experience. A tool that optimizes the cache is needed.
LSCache supports WooCommerce and is designed to optimize WordPress sites. Rewrite rules, located in the root of the .htaccess file, can be used to control c LiteSpeed Cache Engine.
What does this mean? Parameters about what data should be cached, how long this data can be stored, and what actions will make the cache object obsolete can be edited with LSCache.
For example, you can store more objects, increase or decrease the storage time, and make more fine-tuning. Like other cache management plugins, LSCache allows you to change settings for the best possible caching. If done correctly, it noticeably speeds up WordPress sites. But that's not the only reason to optimize caching.
Using caching plugins improves search engine optimization, it leads to higher search engine rankings. This is especially important if you own an online store and want to increase your sales conversion rate.
The most popular options include:
LSCache is a professional plugin and offers an impressive set of parameters for the webmaster. So for beginners, LiteSpeed will seem complicated. But there is no need to worry because in this article we will describe most of the LSCache options and show what you can do to improve the speed of your site.
In the dashboard (located on the left), select the "Plugins" section and click on "Add New". The add plugins menu will open in front of you, and there will be a search box on the right. Enter "LiteSpeed Cache", and then there will be available plugins to install. Hover your cursor over the "Install Now" box.
LiteSpeed is now installed, but the plugin needs to be activated before you can start using it. So do not exit the installation menu until you click on the "Activate" box.
The plugin begins to optimize your site before you even decide to configure anything. But for better optimization, we suggest studying the capabilities of the plugin in depth. LSCache offers two ways to work:
To switch to LiteSpeed Web Server, contact your web hosting company first.
In the dashboard, you will find a separate item – "LiteSpeed Cache". If you click on it, a number of options will open:
Almost all LSCache optimization options are grouped under LiteSpeed Cache Settings. There are 8 tabs in this extremely large section. Let's look at the capabilities of the main items:
Each time you make changes to your caching settings, we recommend that you test your site. Incorrect settings disrupt web pages, so it's worth making sure the site is functioning properly.
A section that actually changes the output code of the site. This can be minimizing and merging CSS and JSS, or "lazy" loading of images.
Let's take a look at the available options for this section:
While the caching settings work "out of the box," "Page Optimization" requires testing. The reason is that different WordPress sites use different themes and plugins. Some optimization settings are useful for pages, but others can slow the site down due to incompatibilities.
So if you own two different sites on WordPress, the feature will work fine on the first site but slow down on the second. We recommend starting with a basic LiteSpeed cache configuration – when only page caching options are enabled. Then you can explore page optimization options and test which ones give you a boost in your site's load speed.
Before dividing them into components, it is useful to understand what is the cache of the site, browser, and server. This information will help you understand how the plugin works:
LSCache refers to a server-side type of caching, it serves stored results quickly so that the pages of the site load more efficiently.
The easiest way to understand the caching process is to look at how the page is served. Suppose you own a site with caching enabled. When a visitor first clicks a link, the following happens:
Because caching is enabled, the server stores this HTML in its RAM. Now, if someone else opens the page, the server no longer needs to process and convert the page into HTML. It simply sends the preformed HTML to the browser.
What happens if you activate the caching feature and then add new information to the site? Will the page be excluded from the cache and, therefore, will the site user see the update?
If caching is configured correctly, the system eliminates such moments on its own. Although caching is essentially storing prepared HTML files, the engine also has a way of emptying the cache (and then restoring it) when certain conditions are met (including publishing new content).
A plugin configured to optimize caching removes the cached version of the main page and archives pages when publishing a new post.
Since search engines analyze how fast pages load, this directly affects your search engine ranking. If you use caching plugins, your overall optimization will improve, and your page ranking will increase accordingly.
Every site owner has an interest in making their product perform well. LSCache is designed to accelerate performance even without specialized knowledge. The plugin saves site maintenance costs, has a user-friendly interface, and works in semi-automatic mode.
Whether you're starting or already running a successful online business, it's important to remember that a good user experience is key to keeping your visitors coming back to your site. LSCache ensures that your site runs quickly so that visitors have a positive experience.
