2 EASY WAYS TO SOLVE “ ADD EXPIRE HEADERS” IN WORDPRESS WEBSITE

Most people don’t understand what are “Expire Headers” and how they help in website speed. Other people are not able to add this feature in WordPress.

Expire headers

Let’s try to make it easy to understand for anyone and everyone.

We need to understand a bit about how browsers help to improve user experience on a website.

All browser applications use a cache to store certain media or resources such as CSS files.

This caching action, decreases page loading time, translating into a delightful user experience.

An important thing to note is that these files are ones that are not changed frequently. A web browser will store these files in the cache. When the page is requested again, the files will be loaded through the browser cache instead of the webserver.

A browser’s cache cannot hold on to a website’s files like images, CSS, Javascript, etc.) forever. These files need to be discarded from the cache after some time. Then fresh data is requested from the webserver.

This is WHERE “Expire Headers” will help you make a faster loading web page.

Got it so far?

Let’s get into a bit more detail and discover HOW the magic happens.

It’s quite simple. All is you need to do, is to set the correct rules in a particular file stored on the webserver. These rules set the date to discard old copies and get fresh copies from the webserver.

HOW WILL BROWSER CACHE EFFECT LOAD SPEED OF A WEBSITE?

When a user clicks on a link in the browser, an HTTP request goes to the web server browser to allow file download. The browser then stores the files in the cache for a specified period.

The browser will serve the files immediately instead of requesting the webserver.

Let us take a look at an example that will help you understand how browser caching can be leveraged for better page speed.
