What is Leverage Browser Caching and how can I enable it for my website?
To understand how Leverage browser caching works, you need to know how web servers and browsers work. Let's go through this process briefly.
To access a website, you need a web browser such as Google Chrome or Mozilla Firefox. A website is usually hosted on a web server, which sends the content to the user's browser every time they visit the website. A website is created using different file types, either dynamic like PHP files or static like HTML, JS, CSS and images. When the pages of a website are small (few KB), they load faster because the web server sends only a small part of the content to the browser. However, if the page is larger (3-4 MB or more) and contains many static resources, it takes longer to load.
Leverage browser caching
In order to shorten the loading time of extensive pages, the Leverage browser caching which allows browsers to download some static resources of visited websites locally. This process aims to reduce the number of requests to the web server when visiting a website, which in turn reduces the amount of data your browser has to download. What is the result? The website loads faster.
The web server itself-in this case, Apache and its mod_expires-enables the use of leverage browser caching. To enable this feature, you must modify your HTTP headers and set expiration times for the file types you want to use. This is done through rules that you add to your .htaccess file.
Create this file in the root directory of the domain you want to use Leverage Browser Cache for, or open it for editing if it already exists. Please copy and paste the following lines into the .htaccess file:
Save the file and voila! You have now implemented Leverage Browser Caching for your website.
