Lecture 6 - Applications #3.1: HTML and HTTP Basics

Hypertext Transfer Protocol (HTTP)

In Lecture #2,, the World Wide Web was used to illustrate the idea of a layered communications architecture. In that lecture, the basic ideas of the original version (0.9, circa 1992) of HTTP were introduced.

To revise, in HTTP 0.9 the GET operation was used to obtain HTML "pages" from a server, eg:

GET /Index.html
    <HTML>
    <HEAD>
    <TITLE>La Trobe University</TITLE>
    </HEAD>
    <BODY>
    <h2>La Trobe University</H2>
    ..........etc

HTTP 0.9 actually defined a few other operations. However, since HTTP 1.0 (RFC 1945) and HTTP 1.1 are now commonly used, we shall defer discussion of them.

The tutorial for this lecture is Tutorial #06.
