For example, forward slash characters are used to separate different parts of a URL (or, more generally, a URI). Unreserved characters have no ...
An Internationalized Resource Identifier (IRI) is a form of URL that includes Unicode characters. All modern browsers support IRIs. The parts of the URL requiring special treatment for different alphabets are the domain name and path. [18] [19] The domain name in the IRI is known as an Internationalized Domain Name (IDN).
In computer hypertext, a URI fragment is a string of characters that refers to a resource that is subordinate to another, primary resource. The primary resource is identified by a Uniform Resource Identifier (URI), and the fragment identifier points to the subordinate resource.
Tells the browser to refresh the page or redirect to a different URL, after a given number of seconds (0 meaning immediately); or when a new resource has been created [clarification needed]. Header introduced by Netscape in 1995 and became a de facto standard supported by most web browsers. Eventually standardized in the HTML Living Standard in ...
The Internationalized Resource Identifier (IRI) is an internet protocol standard which builds on the Uniform Resource Identifier (URI) protocol by greatly expanding the set of permitted characters. [ 1 ] [ 2 ] [ 3 ] It was defined by the Internet Engineering Task Force (IETF) in 2005 in RFC 3987.
