I think Every Body Knows Http Is A Stateless Protocol.

How Many Of them Know Why HTTP Says Stateless ?


Speaking of sessions rated the HTTP protocol is a stateless protocol, and the Internet is a stateless development environment "is often used. It simply means that the HTTP protocol, Internet backbone will be able to maintain the memory of each client, which connects the site and thus treats each application on the website is unique and independent associations connected to the connections that preceded it.
To display a static Web page created by the stateless nature of HTTP protocol is usually not a problem because the page you are viewing is the same regardless of previous operations you have performed.
