⚡ Networking

Networking technologies are protocols, standards, and mechanisms that enable the secure and reliable delivery of web content, manage data exchange between clients and servers, enforce security policies, and optimize connection performance.

They are responsible for request and response handling, encrypted communication, state management, caching and validation, cross-origin access control, connection multiplexing, and transport efficiency, helping ensure consistent and secure interactions across the web.

According to our data, networking technologies are used on 92.1% of all websites.
18.2% of these sites use only one networking technology, 29.7% use two, and 52.1% use three or more simultaneously.
