Please Whitelist This Site?
I know everyone hates ads. But please understand that I am providing premium content for free that takes hundreds of hours of time to research and write. I don't want to go to a pay-only model like some sites, but when more and more people block ads, I end up working for free. And I have a family to support, just like you. :)
If you like The TCP/IP Guide, please consider the download version. It's priced very economically and you can read all of it in a convenient format without ads.
If you want to use this site for free, I'd be grateful if you could add the site to the whitelist for Adblock. To do so, just open the Adblock menu and select "Disable on tcpipguide.com". Or go to the Tools menu and select "Adblock Plus Preferences...". Then click "Add Filter..." at the bottom, and add this string: "@@||tcpipguide.com^$document". Then just click OK.
Thanks for your understanding!
Sincerely, Charles Kozierok
Author and Publisher, The TCP/IP Guide

TCP/IP Hypertext Transfer Protocol (HTTP)
The success of the World
Wide Web is a result of the efficiency
and usefulness of the complete hypermedia system it implements. We examined
in the
last section the basic concepts behind
hypertext, and looked at two of the three major components that comprise
the World Wide Web system: HTML
and URLs.
The third major component of the Web is arguably the most important:
the protocol that actually transfers hypertext documents and other files
between Web servers and Web clients (browsers). This is one of the most
widely-known software protocols in all of networking: the Hypertext
Transfer Protocol (HTTP).
In this section I provide a detailed
description of the Hypertext Transfer Protocol. I begin with an overview
of HTTP and a discussion of its history and versions, and the standards
that define them. I then describe the operation of the protocol in five
subsections. The first discusses HTTP's operation in general terms,
focusing on how connections are established and maintained. The second
describes HTTP messages and how they are formatted, and describes HTTP
methods (commands) and status codes. The third details the many HTTP
headers, which are critically important as they are the primary way
that information is communicated between HTTP servers and clients. The
fourth subsection provides information about how resources, called entities,
are encoded and transferred in HTTP. The final subsection describes
special features and capabilities of the modern HTTP protocol.
