No, HTTP doesn't use WWW; rather, WWW uses HTTP.
Understanding HTTP and WWW
-
HTTP (Hypertext Transfer Protocol): This is the underlying communication protocol that allows web browsers and servers to exchange information. It's the language they use to talk to each other. Think of it as the delivery system. As stated in a reference, "HTTP is the foundation of the World Wide Web, and is used to load webpages using hypertext links."
-
WWW (World Wide Web): This is the system of interconnected hypertext documents accessed via the internet. It's the content and structure using HTTP as its delivery mechanism. Think of it as the information and how it's organized, delivered via HTTP.
A website address like www.example.com uses the www prefix, which indicates that the site likely uses HTTP (or HTTPS, its secure variant) to serve its content. The www itself is not part of the HTTP protocol; it's a convention in the website's URL structure. As one source notes, "WWW stands for World Wide Web, and it's used mostly as a prefix. However, it does indicate that a given website uses HTTP to communicate." Therefore, the WWW relies on HTTP for its functionality.
