Leverage browser caching means storing static files of a website in visitor browser and retrieving them from browser quickly. It is used to speed up each page of a website.

Consequently, when someone comes to your website, so the browser sends the request to load assets such as CSS, HTML, Image, scripts, etc. from the browser. The server then responds to the browser’s request. 

Based on the size of asset requested and server process time, the response may take some time some time to respond. This is the result of increased load on the server and slows down the website at the end of the user.

Here, the browser cache works best, it stores static content on the local machine of users, the first time a user visits a website. Thus, if the website is not properly configured with browser cache and you are testing the speed of site using any online speed testing tools. It will show a warning message to leverage browser caching.

To fix the “Leverage Browser Caching” warning, you have to follow the following two-step:

  1. Change request headers to use cache
  2. Optimize caching policy

1. Change Request Headers to Use Cache

It is the other alternative method that can help you out with cache-controls for setting the caching expiry. If both above methods fail to work for your server, you can use this.

You have to copy and paste the below coding lines on the top of your .htaccess file.
