HTTP is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be.
Despite the XML and Http in the name, XHR is used with other protocols than HTTP, and the data can be of many different types like HTML, CSS, XML, JSON, and plain text.
Understanding the Context
HTTP (Hypertext Transfer Protocol) is a core Internet protocol that defines how data is exchanged between clients and servers on the web. Enables communication between web browsers.
Hypertext Transfer Protocol (HTTP) is the foundation of the World Wide Web, and is used to load web pages using hypertext links. Learn more about HTTP.

Key Insights
HTTP is the protocol behind nearly all communication on the web. A browser loading a page sends an HTTP request for the HTML document, parses the response, then sends additional.
Send an HTTP message: HTTP messages (before HTTP/2) are human-readable. With HTTP/2, these messages are encapsulated in frames, making them impossible to read directly, but the principle.
The request message (for HTTP/1.1 and older) contains the following (i.e. it's in plain text, meaning it is not encrypted; no longer used with HTTP/2 and later):
