Want to learn what is web caching or website caching? what are the different types of web caching? and why do you need to enable a caching service? Then this valuable blog is exclusively for you.

Never forgetif your website takes longer than 3 seconds, an average of 40% – 53% of your visitors will abandon your website. That’s why every website owner wants to load their website extremely fast.

A fast website page speed ensures a better user experience, boosts conversion rate, improves search engine ranking, reduces bounce rate, and increases page views.

Hence, you need to follow best practices to speed up your website. And web caching is one of the key solutions to boost the speed of your website.

Let’s define what is web caching.

What is Web Caching or What is Website Caching

What is Web Caching?

Web caching is the process of storing copies of website content or webpage in a cache or temporary storage for reuse. In fact, this reduces website loading time and server load.

The content of a webpage is cached when a user has accessed it. The next time another user requests the same webpage, the cache will deliver the page right away. This enables the origin server from getting overloaded.

Let me explain with an example. If I ask you what is the result of 3 x 2, you already know the answer is 6 without having to do any calculations. Because you have done the same calculation multiple times. That’s how web caching works.

Quick Note: Technically, cache term means temporary storage or memory that store the data files.

What Are the Different Types of Web Caching?

There’re four different types of web caching: Server Web Caching, Micro Web Caching, Site Web Caching, and Browser Web Caching

Let’s define each one in detail.

#1. Server Web Caching

Server web caching covers different types of caching such as CDN (Content Deliver/Distributed Network), opcode caching, and object caching. Each one saves different content of your website on the server.

The server web caching is controlled by the website owner. And this works best to handle more traffic because when a request is made for accessing a webpage, the server checks its cache storage for the requested webpage before fully processing the visitor’s request.

If requested content (webpage) is available in cache (storage), then the cache serves it faster. However, if it’s not available in the cache, then the request sends to the server to deliver the content. After that, the delivered content will be cached.

#2. Micro Web Caching

Micro web caching is used to store content (static versions of dynamic elements) for a very short period (maximum 10 seconds).

This caching type gives more control to an end-user than a website owner. It’s the perfect option for those websites that regularly update the content like currency exchange sites, stock websites, and breaking news sites.

#3. Site Web Caching

Site web caching (also called page caching) stores the website content when a web page is loaded for the first time. The cache (temporary storage) will quickly load the stored webpage when it’s visited again.

As this caching method is controlled by visitors, that’s why it’s called client-side caching. And the website owner only has to manage how long the website content stays in that cache.

If you frequently change the elements or update the content on your web pages, you should choose a shorter cache expiration period. However, if you never change elements or update the content, then setting up the longest cache expiration period is the right choice.

#4. Browser Web Caching

This method involves a visitor’s web browser that downloads various resources (images, HTML, JavaScript files, CSS stylesheets) of your webpages to their local drive. This speeds up visitors’ browsing and gives a better user experience.
