HTTP is the backbone of the web. It is the universal protocol and standard for transferring text data. Right from the advent of HTTP, the protocol has witnessed massive transformations at different points.
As a result, users get access to HTTP/0.9 to HTTP/2.0. A new HTTP protocol is introduced, which is none other than HTTP/3. It is the next generation web protocol improving performance and web security.
HTTP/3: The Newest And Powerful Version Of HTTP
HTTP/3 changes HTTP a lot and helps web developers and users. HTTP usually performs over Transmission Control Protocol (TCP). But, TCP has established at the beginning of the internet. In the initial time of TCP advent, authors of the TCP could not predict the web’s growth.
When looking into how TCP is outdated, TCP limited HTTP regarding security and speed for a while. But, with the arrival of HTTP/3, HTTP is no longer limited. It accesses the new protocol called QUIC instead of TCP. Google developed the QUIC in 2012 and then introduced many exciting features to HTTP.
What Does HTTP/3 Mean?
As said earlier, HTTP is the essential element of the internet. It dictates how communication devices and platforms exchange information and fetch the necessary resources. In simple words, it allows the users to load the websites.
In the row of the different HTTP protocols, HTTP/3 is the newcomer. It affects how web browsers and servers communicate. It also comes with significant upgrades for the user experience, such as reliability, security, and performance. It brings many significant changes to make the users enjoy the best experience.

What Is New In HTTP/3?
After the approval of HTTP/2 in 2015, HTTP/3 will be the first and best upgrade to HTTP. The significant difference between HTTP/3 and other HTTP protocols is that it runs on QUIC. QUIC is the new transport protocol designed for mobile-heavy internet usage. Unlike before, people now carry smartphones and switch from one network to another constantly because they move throughout the day.
It was not the case during the first Internet protocols launch because devices were less portable. So, switching between the networks is not often. QUIC in the HTTP/3 relies on the UDP (User Datagram Protocol), not TCP. Do you know that switching to UDP enables faster connections and user experience when browsing online? Since HTTP/3 is in the developing stage, you will soon witness a host of changes in your browser.
Attractive Features Of The HTTP/3
Here are the primary and exciting features of HTTP/3, which keep the new HTTP protocol at the top position.
- Faster Request Multiplexing
Browsers could send only requests to the server until before the arrival of HTTP/2. As a result, the website loaded slower as the browser loaded one asset at once. HTTP/2 protocol offered a better solution to all these problems and provided the ability for the sites to load more than one asset at a time. However, TCP has not made for the concern factors.
TCP would make the browser redo all the requests whenever a request fails. HTTP/3 has sorted out all these issues. By replacing QUIC for TCP, the browsers now redo the failed request and ensure reliable and faster service.
- Quick Encryption
HTTP/3 optimizes the handshake, which lets browsers’ HTTP requests be encrypted. The new protocol QUIC combines the initial connection with the TLS handshake. Thus, it makes the connection secure and faster by default.
- Browser And Server Support
HTTP/3 brings a big revolutionary change to enhance web performance and security. If you want to set up the HTTP/3 website, you need server and browser support. At present, Google Cloud, Fastly, and Cloudflare support HTTP/3.
In terms of browser support, Firefox, Chrome, Opera, Edge, and specific mobile browsers support HTTP/3. You can check the updated browser’s supportability. At present, HTTP/3 enables the experimental protocol on Chrome.
Why Does HTTP/3 Matter?
HTTP/3 is the newest iteration of the HTTP protocol. It designs to address some of the significant limitations of the HTTP/2 to enhance the performance and security of the HTTP protocol. The new protocol sorts out the TCP head-of-the-blocking problems, still available in HTTP/2. It also improves the HTTP protocol in many ways, such as time-sensitive requests and faster loading.
Even though the security and performance of HTTP/3 matter a lot, it has a considerable drawback. It is nothing but high CPU usage on both client and server sides. The high CPU consumption is noticed on the service side highly. More web servers monitor the CPU and the number of requests per second.
Usually, the client-side will not do it much. But, the overhead is easy to sort out over time. Since technology evolves continuously, you will find and get a solution to your problem. Are you thinking about implementing HTTP/3? You can expect the changes to come into effect once IETP approves the protocol.

Why Do You Need The New Version Of HTTP?
- The availability of QUIC in HTTP/3 helps fix some of the most significant shortcomings in the previous version of the protocol called HTTP/2. Some of them are: developing a plan for the sluggish performance when switching from WI-Fi to cellular data on your mobile and minimizing the effects of packet loss.
- QUIC lets TLS version negotiation occur simultaneously because of the transport and cryptographic handshakes.
- The new approach of the QUICK to handshakes will render encryption by default. It is a massive upgrade of HTTP and helps minimize the risk of attacks.
- Zero round trip time is another most significant reason to access HTTP/3. Clients will skip the handshake requirements for the server they have connected to.
Now, you realize the importance of HTTP/3 and how it will change the internet in the future. Are you thinking about switching to the new protocol without making any changes to the origin?
