  URL: Uniform Resource Locator(RFC 1738)
Uniform Resource Location (URL) is the syntax and semantics for a compact string representation for a resource available via the Internet.
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".

  Uniform Resource Locator - Wikipedia, the free encyclopedia
A URL is the complete colection of parameters that locates an individual Resource (document, image, web page) on the World Wide Web.
A fraction of a URI or URL is known as the Domain Name.
URL's uniformity in syntax creates a simple and organized structure upon which Communication Protocols can be created.

A Uniform Resource Locator, URL (either pronounced as "earl" — IPA: /ɝl/ (American) or /ɜːl/ (British) — or spelled out), or Web address, is a standardized address name layout for some resource (such as a document or image) on the Internet (or elsewhere).
URLs are classified by the "scheme" which typically identifies the network protocol used to retrieve the resource over a computer network.
URLs in general are case-sensitive; however it is up to the server administrator to decide to respect case when responding to requests.

 Persistent Uniform Resource Locator - Wikipedia, the free encyclopedia
location-based Uniform Resource Identifier or URI) that does not directly describe the location of the resource to be retrieved, but instead describes an intermediate (more persistent) location which, when retrieved, results in redirection (e.g.
PURLs are an interim measure - while Uniform Resource Names (URNs) are being mainstreamed - to solve the problem of the lack of persistence (over time) of URIs in location-based URI schemes like HTTP.
Popular http-servers silently add a "missing" trailing slash to URLs, or strip an extraneous trailing slash as needed, but the specification RFC 3986 allows them to refer to different resources.

 Uniform Resource Locator Summary
A Uniform Resource Locator (URL) is a string of characters conforming to a standardized format, which refers to a resource on the Internet (such as a document or an image) by its location.
A URL is classified by its scheme, which typically indicates the network protocol used to retrieve a representation of the identified resource over a computer network.
Some of the first URL schemes, such as the still-popular "mailto", "http", "ftp", and "file" schemes, along with the general syntax of URLs, were first detailed in 1994 in Request for Comments RFC 1630, superseded within a year by the more refined RFC 1738 and RFC 1808.

 RFC 1738 (rfc1738) - Uniform Resource Locators (URL)   (Site not responding. Last check: 2007-10-21)
A file URL takes the form: file:/// where is the fully qualified domain name of the system on which the is accessible, and is a hierarchical directory path of the form //.../.
BNF for specific URL schemes This is a BNF-like description of the Uniform Resource Locator syntax, using the conventions of RFC822, except that "" is used to designate alternatives, and brackets [] are used around optional or repeated elements.
In such cases, it is convenient to have a separate syntactic wrapper that delimits the URL and separates it from the rest of the text, and in particular from punctuation marks that might be mistaken for part of the URL.

 Web Naming and Addressing Overview (URIs, URLs, ...)
Uniform Resource Identifiers (uribof) Bof at IETF 56 in San Francisco
When embedded within a base document, a URL in its absolute form may contain a great deal of information which is already known from the context of that base document's retrieval, including the scheme, network location, and parts of the url-path.
In situations where the base URL is well-defined and known to the parser (human or machine), it is useful to be able to embed URL references which inherit that context rather than re-specifying it in every instance.

 DP87: Addition of Subfield $l (Uniform Resource Locator) in Linking Entry Fields 76X-78X
Because of the volatility of location information (there is the potential of the resource being moved from one machine to another or the compression changed) only the unique elements are recorded in field 856, and information in a document locator file supplies the additional information for the specific item.
A resource identified by a URN may reside at many locations under any number of filenames and may move any number of times during its lifetime.
The URL identifies the location for an instance of a resource identified by the URN.

 URL (Java 2 Platform SE v1.4.2)
A resource can be something as simple as a file or a directory, or it can be a reference to a more complicated object, such as a query to a database or to a search engine.
A URL can optionally specify a "port", which is the port number to which the TCP connection is made on the remote host machine.
Two URL objects are equal if they have the same protocol, reference equivalent hosts, have the same port number on the host, and the same file and fragment of the file.

A Uniform Resource Locator (URL) is a string of text that is used to locate a resource on the Internet, such as a Web page, document, or image.
There are various types of URLs, but the most widely used is a HyperText Transfer Protocol (HTTP) URL, also known as a Web address.
An HTTP URL can contain two additional pieces of information: a query that gives instructions to a database, program, or script residing on the server; and an anchor that takes you to a particular location on a Web page.

 Uniform Resource Locator (Linux Reviews)
Uniform Resource Locator (URL) is a technical, Web-related term used in two distinct meanings:
These names were misleading, however, because not all identifiers were locators, and even for those that were, this was not their defining characteristic.
Every URI (and therefore every URL) begins with the scheme name that defines its namespace, purpose, and the syntax of the remaining part of the URI.
