All web traffic over the internet uses the well-known HTTP protocol.
HTTP/1.1 has been the standard web communications protocol since then.
The most recent revisions were made in 2014.
Tip: A web resource is any file used in the display of a webpage.
For example, this includes the HTML code, images, styling information, and scripts.
Implementation in browsers
All modern browsers support HTTP/2.
Unfortunately, the implementation rate on websites is less universal.
Nevertheless, users can get the benefits of HTTP/2 on those websites that have been configured to use it.
While the HTTP/2 protocol itself doesnt require the use of encryption, all web client implementations of it do.
As such the HTTP/2 protocol can only be used over HTTPS connections.
