URL Resources
A URL can be broken into several parts. For example: the URL
http://www.amx.com/company-info-
home.asp
. This URL indicates that the protocol in use is
http
(HyperText Transport Protocol) and that
the information resides on a host machine named
www.amx.com
. The image on that host machine is
given an assignment (
by the program
) name of
company-info-home.asp
(Active Server Page)
.
The exact meaning of this name on the host machine is both protocol dependent and host dependent. The
information normally resides in a file, but it could be generated dynamically. This component of the
URL is called the file component, even though the information is not necessarily in a file.
A URL can optionally specify a port, which is the port number to which the TCP connection is made on
the remote host machine. If the port is not specified, the default port for the protocol is used instead. For
example, the default port for http is 80. An alternative port could be specified as:
http://www.amx.com:8080/company-info-home.asp.
Special escape sequences
The system has only a limited knowledge of URL formats in that it transparently passes the URL
information onto the server for translation. A user can then pass any parameters to the server side
programs such as CGI scripts or active server pages. However; the system will parse the URL looking
for special escape codes. When it finds an escape code it replaces that code with a particular piece of
panel, button, or state information.
For example, "http://www.amx.com/img.asp?device=$DV" would become "http://www.amx.com/
img.asp?device=10001". Other used escape sequences include:
Any legal HTTP syntax can be used.
