Web Services in Apahe

Web Services in Apahe: "Ask five people what 'web services' are and you will likely get at least six different opinions. Because the term evokes such ambiguity, we need to set ground rules for this article and define what we mean by 'web services'. Therefore, for the purposes of this book, 'web services' are the interactive exchange of messages from one system to another using the Internet as the network transport and HTTP/HTTPS as the messaging protocol. Message exchange transpires without human intervention and may be one-way—that is, called without an immediate response expected—or two-way."
