The Hypertext Transfer Protocol (HTTP) is an application layer protocol for distributed, collaborative, hypermedia information systems. HTTP is a request response standard typical of client-server computing.

When someone else looks at your web site, this is the location they will be accessing. In order for a website to be accessible to visitors, it must be published to the correct directory, the "document root."

Configuration File This article explains configuration files on a Linux system that control user permissions, system applications, daemons, services, and other administrative tasks in a multi-user, multi-tasking environment. These tasks include managing user accounts, allocating disk quotas, managing e-mails and newsgroups, and configuring kernel parameters.
