.\"O A Uniform Resource Identifier (URI) is a short string of characters
.\"O identifying an abstract or physical resource (for example, a web page).
.\"O A Uniform Resource Locator (URL) is a URI
.\"O that identifies a resource through its primary access
.\"O mechanism (e.g., its network "location"), rather than
.\"O by name or some other attribute of that resource.
.\"O A Uniform Resource Name (URN) is a URI
.\"O that must remain globally unique and persistent even when
.\"O the resource ceases to exist or becomes unavailable.

.\"O URIs are the standard way to name hypertext link destinations
.\"O for tools such as web browsers.
.\"O The string "http://www.kernelnotes.org" is a URL (and thus it
.\"O is also a URI).
.\"O Many people use the term URL loosely as a synonym for URI
.\"O (though technically URLs are a subset of URIs).

.PP
.\"O URIs can be absolute or relative.
.\"O An absolute identifier refers to a resource independent of
.\"O context, while a relative
.\"O identifier refers to a resource by describing the difference
.\"O from the current context.
.\"O Within a relative path reference, the complete path segments "." and
.\"O ".." have special meanings: "the current hierarchy level" and "the
.\"O level above this hierarchy level", respectively, just like they do in
.\"O Unix-like systems.
.\"O A path segment which contains a colon
.\"O character can't be used as the first segment of a relative URI path
.\"O (e.g., "this:that"), because it would be mistaken for a scheme name;
.\"O precede such segments with ./ (e.g., "./this:that").
.\"O Note that descendants of MS-DOS (e.g., Microsoft Windows) replace
.\"O devicename colons with the vertical bar ("|") in URIs, so "C:" becomes "C|".

.\"O There are many different URI schemes, each with specific
.\"O additional rules and meanings, but they are intentionally made to be
.\"O as similar as possible.
.\"O For example, many URL schemes
.\"O permit the authority to be the following format, called here an
.\"O .I ip_server
.\"O (square brackets show what's optional):

.HP
.IR "ip_server = " [ user " [ : " password " ] @ ] " host " [ : " port ]
.PP
.\"O This format allows you to optionally insert a username,
.\"O a user plus password, and/or a port number.
.\"O The
.\"O .I host
.\"O is the name of the host computer, either its name as determined by DNS
.\"O or an IP address (numbers separated by periods).
.\"O Thus the URI
.\"O <http://fred:fredpassword@xyz.com:8080/>
.\"O logs into a web server on host xyz.com
.\"O as fred (using fredpassword) using port 8080.
.\"O Avoid including a password in a URI if possible because of the many
.\"O security risks of having a password written down.
.\"O If the URL supplies a username but no password, and the remote
.\"O server requests a password, the program interpreting the URL
.\"O should request one from the user.

.\"O The second format (e.g., <file:/etc/passwd>)
.\"O is a correct format for referring to
.\"O a local file.
.\"O However, older standards did not permit this format,
.\"O and some programs don't recognize this as a URI.
.\"O A more portable syntax is to use an empty string as the server name,
.\"O for example,
.\"O <file:///etc/passwd>; this form does the same thing
.\"O and is easily recognized by pattern matchers and older programs as a URI.

.\"O Most tools that accept URIs support a set of internal URIs
.\"O (e.g., Mozilla has the about: scheme for internal information,
.\"O and the GNOME help browser has the toc: scheme for various starting
.\"O locations).
.\"O There are many schemes that have been defined but are not as widely
.\"O used at the current time
.\"O (e.g., prospero).
.\"O The nntp: scheme is deprecated in favor of the news: scheme.
.\"O URNs are to be supported by the urn: scheme, with a hierarchical name space
.\"O (e.g., urn:ietf:... would identify IETF documents); at this time
.\"O URNs are not widely implemented.
.\"O Not all tools support all schemes.

.\"O The URI syntax was designed to be unambiguous.
.\"O However, as URIs have become commonplace, traditional media
.\"O (television, radio, newspapers, billboards, etc.) have increasingly
.\"O used abbreviated URI references consisting of
.\"O only the authority and path portions of the identified resource
.\"O (e.g., <www.w3.org/Addressing>).
.\"O Such references are primarily
.\"O intended for human interpretation rather than machine, with the
.\"O assumption that context-based heuristics are sufficient to complete
.\"O the URI (e.g., hostnames beginning with "www" are likely to have
.\"O a URI prefix of "http://" and hostnames beginning with "ftp" likely
.\"O to have a prefix of "ftp://").

.\"O It is sometimes possible to construct a URL such that an attempt to
.\"O perform a seemingly harmless operation, such as the
.\"O retrieval of an entity associated with the resource, will in fact
.\"O cause a possibly damaging remote operation to occur.
.\"O The unsafe URL
.\"O is typically constructed by specifying a port number other than that
.\"O reserved for the network protocol in question.
.\"O The client unwittingly contacts a site that is in fact
.\"O running a different protocol.
.\"O The content of the URL contains instructions that, when
.\"O interpreted according to this other protocol, cause an unexpected
.\"O operation.
.\"O An example has been the use of a gopher URL to cause an
.\"O unintended or impersonating message to be sent via a SMTP server.
