Hypertext Transfer Protocol is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers.
Cross-site HTTP requests are HTTP requests for resources from a different domain than the domain of the resource making the request (e.g., using JavaScript, an HTTP request is made from to that would otherwise be blocked due to cross-site scripting limitations but is possible due to CORs).
Web Sockets
A protocol that allows for a persistent TCP connection between server and client so they can exchange data at any time (e.g., The server can reach out to the client to invoke a change v.s. the client only being able to request changes).
