Introduction

In the process of phishing, we have identified the construction of both the type of Web site and e-mail contents that are used to obtain successful theft of information. In Chapters 2 and 3, we demonstrated the use of HTML, JavaScript, and very basic HTTP header fields. HTTP is the protocol that performs the requesting and retrieving functions between a client and server when you re browsing the Web. Essentially, it is the protocol that is primarily used when we surf the Internet.

Within the big picture of the Internet and computing, HTTP is a very simple and organized protocol; it is one of the better examples of a successful evolution to content delivery due mainly to its continued popularity as the World Wide Web and the need for security-conscious standards have evolved. The learning challenge is not necessarily HTTP as a protocol; it is the markup language and its extensibility that is delivered via HTTP. The more unusual concept of HTTP and the Web is that HTTP s delivery method is not via one central computer, but a globalization of computers that form the Web. This allows redundancy and the ability for reliable document delivery.
