Hypertext Transfer Protocol (HTTP) is the protocol implied by the familiar "http://" prefix typed into a browser’s address bar to request data from a remote server and display information on screen. HTTP appears as the basic mechanism that lets a user reach personal websites, artworks, and other web pages by entering an address and receiving content from elsewhere on the network.
What can be said is that HTTP is presented as part of the everyday experience of early web navigation: a URL is entered, data is delivered from a server, and the browser renders pages such as self-introductions, diaries, guestbooks, and link collections. In this sense, HTTP is tied to the idea of the URL as both a locator of information and a kind of address indicating that someone or something is present at a particular place on the web.
HTTP is also linked to the preservation and accessibility of web-based works. Because content is reached through URLs and server locations that can change or disappear, HTTP becomes part of the infrastructure that determines whether a work remains reachable. For network art and other digital works, this makes HTTP not just a transport mechanism, but a layer that supports how works are found, viewed, and maintained over time.
