Revision Content

The target of an HTTP request is called a "resource", which nature isn't defined further; it can be a document, a photo, or anything else. Each resource is identified by a Uniform Resource Identifier ({{Glossary("URI")}}) used throughout HTTP for identifying resources.

URIs, URLs and URNs

The most common form of URI is the Uniform Resource Locator ({{Glossary("URL")}}), which is known as web address.
