CGI
is not actually a programming language- the three
letters stand for Common Gateway Interface. CGI
is actually a method or convention for passing
data back and forth between the server and the
application (a client) and is part of the Web's
Hypertext Transfer Protocol (HTTP). CGI allows
you to use a program behind the scenes to perform
tasks that cannot be done through HTML. |
If your web server allows
you to use your own CGI programs, you are almost
ready to roll. Now you are left with a few options:
|
| |
We
can use CGI programs, which permits interactivity
between a client and a host operating system through
the World Wide Web via the HTTP. We can write
CGI programs in Perl, Java, Visual Basic and also
can use script written by others. We can use CGI
script for processing the form data and responding
to the client in the form of dynamically generated
HTML documents, sound, pictures and so on. |
Apart
from them we can add guest books, page counters,
a form to let visitors send you mail or place
an order, reading and writing data files, searching
for data in files and other interactive elements
to your website using CGI program. Applications
such as how to password protect an area on your
website, how to build an online catalog with a
shopping cart, how to work with cookies, how to
protect your site from spammers etc. can be added
advantage to your business. |
