The very good news is that you can full the system in a couple of uncomplicated ways. You are going to require to check whether or not your server now supports the newest HTTP protocol, then operate a handful of instructions to allow it (assuming your assistance service provider has not already accomplished so).

In this article, we’ll clarify what HTTP/2 is and its rewards. Then, we’ll talk about how to configure your server to use the protocol if the choice is offered. Let us get started off!

An Introduction to HTTP/2

HyperText Transfer Protocol (HTTP) is the fundamental protocol utilised by the web. It defines how messages are formatted and transmitted, and what actions net servers and browsers must just take in response to various commands.

For instance, when you enter a URL in your browser, this sends an HTTP command to the internet server directing it to fetch and transmit the requested world-wide-web web site.

The most current edition of HTTP is HTTP/2, which was printed as RFC 7540 in 2015. It is built to strengthen upon the functionality of the first HTTP protocol by providing a much more successful way of transmitting knowledge above the online.

The Benefits of Employing HTTP/2

HTTP/2 is an optimized, binary (rather than textual) protocol that lets for multiplexing of requests and responses, as very well as header compression. It features quite a few strengths more than earlier versions of the protocol.

First, it facilitates decreased latency in between servers and clientele. This usually means that web-sites are capable to load more immediately and successfully. With it, website servers can “push” means to consumers right before they even ask for them, more lowering any delay.

A different gain of HTTP/2 is that it presents sizeable general performance improvements in excess of HTTP/1.1. For occasion, the new header compression algorithm decreases the dimension of headers to improve effectiveness. All of these improvements in velocity and overall performance can make improvements to your site’s Main World-wide-web Vitals scores and boost your site’s search rankings.

On the other hand, if you want your website to reap these added benefits, your server have to be configured to help HTTP/2. It is also worth noting that most major browsers, including Chrome, Edge, Safari, and Firefox, guidance HTTP/2.

How to Configure WordPress to Use HTTP/2 (In 4 Steps)

In order to take edge of HTTP/2, your website server must assistance it. If you are making use of Apache or Nginx, you will need to have to upgrade to the most up-to-date variation to enable guidance. Let’s get a look at how to go about this in four measures.

Step 1: Check to See If Your Server Supports HTTP/2

To start, it’s a good idea to determine irrespective of whether your recent server supports the new protocol. To check out if your world-wide-web server previously supports HTTP/2, you can use the KeyCDN on the net HTTP/2 Test device:

The KeyCDN HTTP/2 test tool.

Simply enter the URL of your web page, then click on on the Take a look at button.

If your server’s latest configuration supports the HTTP/2 protocol, a environmentally friendly notification bar will appear beneath the URL area to affirm this. Alternatively, you will see a purple notification bar that states “HTTP/2 protocol is not supported.”

Move 2: Be certain You are Serving Your Site About a Secure TLS/SSL Link

As we talked about, the the greater part of browsers support HTTP/2, but only when the relationship is encrypted. Even though HTTP/2 does not technically have to have encryption to perform, all major web browsers have manufactured it a prerequisite.

As a result, if you have not already, you will need to have to put in a Safe Sockets-Layer (SSL) certification on your WordPress web page. The method for executing this will change based on your web hosting provider.

The good news is, though, most world wide web hosts include things like an SSL or Transportation Layer Security (TLS) certification for free of charge in their internet hosting programs. Both of those are satisfactory for your desires. If your service provider doesn’t provide both alternative you can also get 1 from Let’s Encrypt.

Stage 3: Empower HTTP/2

Ahead of you go ahead, it is also critical to observe that several on-line company suppliers that operate servers on-premise (or in the cloud) update their servers to quickly increase support for HTTP/2. Consequently, it would be intelligent to examine with your host to ascertain whether or not you have to have to do nearly anything to ensure your WordPress website supports HTTP/2.

At the time you’ve verified that your server supports the protocol and you’re serving your site more than a safe link, you can enable it for use on your WordPress web-site. The process for accomplishing so will rely on regardless of whether you’re utilizing an Apache or Nginx server.

Nginx servers incorporate native support for HTTP/2. On the other hand, Apache servers use their very own mod_http2 module.

To allow the module in Apache, you can commence by managing the subsequent command in your terminal:

$ sudo a2enmod http2

The higher than is for Ubuntu distributions. On the other hand, there are different versions for retrieving the Apache configuration webpage primarily based on your Linux distribution:

/and so forth/apache2/httpd.conf
/and many others/httpd/httpd.conf
/and so on/httpd/conf/httpd.conf

Track down the subsequent, then eliminate the pound image (or hashtag) from the beginning of the line:

#LoadModule http2_module modules/

This will load and activate the module for you to use. Next, enter the adhering to line to your Apache configuration file:

Protocols h2 http/1.1

This directive ensures that the safe protocol will be preferred. Up coming, wherever you set this directive (this sort of as inside the virtual host for your server configuration), you can nest the next:

Protocols http/1.1

Protocols h2 http/1.1

Ultimately, you can run the following:

# company httpd restart
# systemctl restart httpd
# sudo company apache2 restart

This will restart Apache.

Alternatively, if you want extra control above HTTP/2 implementation for WordPress specially, you can install the HTTP/2 Server Drive plugin:

The Server Push Reload WordPress plugin.

The free tool lets you leverage the Server Drive mechanisms launched with this protocol. For occasion, you can use it to establish which means, this kind of as JavaScript and CSS data files, are server pushed to the browser.

Phase 4: Check To Validate HTTP/2 Is Functioning

When you’re finished, regardless of the pathway you took to permit HTTP/2, you’ll possibly want to operate a take a look at to test no matter if your endeavours were successful. This way, you can be confident that every little thing is properly configured and working as it should really.

To do so, you can use the very same KeyCDN Test Resource that we mentioned in Move 1. If all the things is in order, your take a look at outcomes should really show the environmentally friendly notification bar that suggests “HTTP/2 protocol is supported.” That’s it!


When you control a WordPress internet site, it’s vital that you carry out sure steps to make certain it operates securely and at its utmost opportunity. A single of the means you can do that is by enabling the newest HTTP protocol.

As we discussed in this write-up, you can configure WordPress to use HTTP/2 in four very simple measures:
