The Internet Domain Name lookup facility printed on
the reverse of this page makes use of a Common
Gateway Interface (CGI) script installed on the remote server
that hosts the online version of this Webpage. It is able to interrogate some of the
Internet Domain Name Registries. If the Domain Name is registered,
basic information is returned to a 'results' Webpage.
It is potentially possible to maintain a record of all commands processed
by a CGI script. For this particular page there is currently no such
record being saved. In the event that this were to change, an announcement would
appear here. Some links may contain an identifier that will enable a
remote server to discover the source of a visitor and in some cases,
reward the referrer. These two paragraphs were added on 3rd
The rest of this explanation was first published on Friday, 16th
June 2006. It appeared in printed format on the reverse of a Webpage,
created on 4th April 2006, that contained a schedule
of Networking and Learning Events for April-June 2006. That Webpage
was last updated on 21st June 2006 and is published at www.A4M.info/events/060621.htm,
In its online format, the underlined text tells the reader that
further information can be found by navigating with the computer mouse
control to other Webpages, elsewhere on the Internet. By hovering the
mouse over the underlined text most Web browsers will show the
destination URL in the status bar along the bottom of the screen.
The original design of the HyperText Markup Language (HTML) engineered
a change of colour for the text to indicate that the user had already
visited the linked information. A link to another document can also be
engineered from a graphic. Again, the destination URL (Uniform
Resource Locator) should be shown in the status bar.
The printed reproduction of a Webpage is really only for illustration
purposes because much of the important information is on related
Webpages, accessible only by means of the described Hyperlink
navigation system that has made the Internet so powerful.
The practice by some web developers of deviating from the original
HTML format may, sometimes, make it harder for new users to easily
navigate the Web.
