Class: UniversalResourceLocator
Documentation: A telecommunications address specified according to Internet standard RFC 1738 [http://www.isi.edu/in-notes/rfc1738.txt]. The URL specifies the protocol and the contact point defined by that protocol for the resource. Notable uses of the telecommunication address data type are for telephone and telefax numbers, e-mail addresses, Hypertext references, FTP references, etc.
The Internet standard RFC 1738 [http://www.isi.edu/in-notes/rfc1738.txt] defines URL as follows:
Just as there are many different methods of access to resources, there are several schemes for describing the location of such resources.
The generic syntax for URLs provides a framework for new schemes to be established using protocols other than those defined in this document.
URLs are used to "locate" resources, by providing an abstract identification of the resource location. Having located a resource, a system may perform a variety of operations on the resource, as might be characterized by such words as "access", "update", "replace", "find attributes". In general, only the "access" method needs to be specified for any URL scheme.
