This tutorial has been prepared for computer science graduates and web developers to help them understand the basic to advanced level concepts related to Hypertext Transfer Protocol (HTTP).
The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems.
This is the foundation for data communication for the World Wide Web (i.e. internet) since 1990. HTTP is a generic and stateless protocol which can be used for other purposes as well using extensions of its request methods, error codes, and headers.
