Understanding HTTP and WebDAV

HTTP is the underlying protocol used by the World Wide Web. HTTP defines how messages are formatted and sent, and how Web servers and browsers respond to various commands; for example, when you type a URL in your browser, an HTTP command is sent to the Web server, which directs the server to find and display the requested Web page.

WebDAV, an extension to HTTP, is a set of commands designed to enable computers to exchange information. Clients use an Internet browser or a Microsoft product such as Office 2000 to create, remove, and query information about remote resources. Resources are documents and e-mail in Information Store that users access through an HTTP virtual server.
