For example, once you enter a URL in your browser, this actually sends an HTTP command to the online server directing it to fetch and transmit the requested website.

The opposite main standard that controls how the planet Wide Web works are HTML, which covers how sites are formatted and displayed.

HTTP may be a Stateless Protocol

HTTP is named a stateless protocol because each command is executed independently, with none knowledge of the commands that came before it.

This is often the most reason that it's difficult to implement internet sites that react intelligently to user input.

This shortcoming of HTTP is being addressed during a number of latest technologies, including ActiveX, Java, JavaScript, and cookies.
