Passing Values

Hypertext Transfer Protocol (HTTP), the underlying protocol used by the World Wide Web, is a stateless protocol. This means that each page request made to a web server is independent from any others and has no information about anything that has occurred previously. Consequently, no information is kept about what data has been entered or what events have occurred prior to the current page request.

The capability to track state, which includes such things as user actions or entered information, is the cornerstone of any modern application. For us to be able to transform our old, static web site into a responsive, data-driven web application, we have to be able to track and pass information from one page to the next.
