You can check whether the website is communicating with HTTP / 2.
What is HTTP / 2?
The second official version of the HTTP Hypertext Transfer Protocol, built on a series of advanced technologies to make web access faster.
This new technology replaces the HTTP / 1.1 standard that was previously widely used in the World Wide Web system.
Therefore, HTTP / 2 was created to reduce latency, increase efficiency, and improve website performance.
Features of HTTP / 2
- HTTP / 2 is a binary data transfer protocol.
Unlike HTTP / 1.1, which uses “text data”, which degrades performance when applied in a network environment, HTTP / 2 uses “binary data” to perform tasks more efficiently and save time.
- HTTP / 2 compresses HTTP headers.
- Unlike HTTP / 1.1, which can process only one request / response pair at a time, HTTP / 2 is asynchronous, so it can process sending and receiving at high speed.
- HTTP / 2 has a new feature called server push.
