The following information is an edited version of the URL
guide that is provided by the NCSA Mosaic package. We believe
that the service abstraction provided by the URL concept is a good
one, and hope to provide more search and retrieval products under it
that take advantage of this paridigm in the future.
What's a URL? A URL is a Uniform Resource Locator. Think of
it as a networked extension of the standard filename concept:
not only can you point to a file in a directory, but that file and
that directory can exist on any machine on the network, can be served
via any of several different methods, and might not even be something
as simple as a file: URLs can also point to queries, documents stored
deep within databases, the results of a finger or archie
command, or whatever.
Since the URL concept really pretty simple ("if it's out there, we can
point at it"), this beginner's guide is just a quick walk through some
of the more common URL types and should allow you to be creating and
understanding URLs in a variety of contexts very quickly.
