The target of an HTTP request is called a "resource", whose 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.
-The identity and the location of resources on the Web are mostly given by a single URL (Uniform Resource Locator, a kind of URI). There are sometimes reasons identity and location are not given by the same URI: HTTP uses a specific HTTP header, {{HTTPHeader("Alt-Svc")}} when the resource requested wants the client to access it at another location.
