The HyperText Transfer Protocol, or HTTP, is the backbone of the World
Wide Web. HTTP is the language that each web browser (or other web
client) uses to communicate with servers around the world. All web
programmers, administrators, and application developers need to be
familiar with HTTP in order to work effectively.The HTTP Pocket
Reference not only provides a solid conceptual foundation of HTTP, it
also serves as a quick reference to each of the headers and status codes
that comprise an HTTP transaction. The book starts with a tutorial of
HTTP, but then explains the client request and server responses in more
detail, and gives a thorough technical explanation of more advanced
features of HTTP (such as persistent connections and caching).Most
people use the Web every day without knowing anything about HTTP, but
for those who need to get "beyond the browser," this book is the place
to start.
