Hyper Text Transfer Protocol

What does Http do? HTTP is an application layer protocol, which sits on top of the Transport Layer Protocol (TCP). TCP provides a reliable connection between two machines, and HTTP uses this connection to exchange information between the client(web browsers) and web servers.

HTTP is a stateless protocol, which means that the server does not keep any data (state) between two requests. This makes HTTP very efficient since the server does not have to remember anything about the client.

Below are the different versions of Http Protocols :

Currently, the majority of the services(Apis) are built on Http/2 only, and still, Http3 is under development also all the major web servers support the newer version of Http 3.

But why Http 3 now? , Because the newer version is improved by 40% more efficiently than the previous versions. If you are developing a web application, you should consider using HTTP/3. This will help to ensure that your application is as efficient and reliable as possible.

Features of Http/3

  • Header compression: Headers are compressed to reduce the amount of data that needs to be sent.
  • Multiplexing: Multiple requests can be sent over the same connection, which reduces the number of round trips that need to be made.
  • Server push: The server can push resources to the client before the client requests them, which can reduce latency.
  • Connection migration: If a connection is interrupted, it can be migrated to a new connection without losing data.

Benefits of Http/3

  • Improved performance: HTTP/3 can improve performance by up to 40% compared to HTTP/2.
  • Reduced bandwidth usage: HTTP/3 can reduce bandwidth usage by up to 30% compared to HTTP/2.
  • Improved reliability: HTTP/3 can improve reliability by reducing the number of dropped packets.

Challenges for Http3 :

  • Not yet widely supported: HTTP/3 is still under development, and it is not yet widely supported by browsers and servers.
  • Requires new infrastructure: HTTP/3 requires new infrastructure, such as QUIC-enabled proxies and servers.
  • May not be compatible with all applications: HTTP/3 may not be compatible with all applications, such as those that use older versions of HTTP.

In our next blog, I will try to implement the .Net core API with the Http/3 version.
