As Web professionals, every day we use software that implements the HTTP protocol. Usually, the details of HTTP are hidden from our view: browsers, servers, programmers, and system administrators make it so the average user thinks 'http' is simply a 4 letter symbol that goes at the beginning of a link. However, to a Web programmer or even Web designer in these days of client side XMLHTTPRequest scripting, knowledge of the details of how HTTP messages are constructed and interpreted can be useful.

This session provides an introduction to the basics of HTTP including its concept of requests and responses, agents, error signaling and cache control, character sets, and media types. We'll cover techniques to inspect HTTP transmissions "on-the-wire" to help troubleshoot and debug your applications. We'll cover tips on how to speed up your website and applications by interpreting the contents of the communications between browsers and servers..
