We have already discussed, in recent time CGI is used in a great deal to facilitate the interactive program. The technological advancement has taken it to a new height. But as a common man you may raise a question, why shall I use the CGI? In recent years the uses of CGI can be duplicated, means it can be put for similar uses in other fields with the help of newer technology. The main advantage of using CGI is that all your reader will be able to use the program, though there may be some exception. There is a possibility of turning off JavaScript and Active-X within the browser. Other type of problem that you may face is that many of the browsers may not be able to support newer technologies. You will also see that such technologies are not allowed by company firewalls to work within their system due to security reason. But the CGI scripts will not face such problems as such scripts run with the help of external server. The other advantage you will find with the CGI that it has no limitation of browser and firewall.

From the above discussion you must not draw any conclusion that the CGI script does not suffer from any disadvantages. The greatest disadvantage of the CGI scripts is that they put excessive pressure or loads on the server. Programs which are poorly written create much problem. It has been seen that the browser time out the usual time of 5 minutes. Very often the server shuts the faulty scripts off. In this situation we cay say that the browser based technology have advantages over the CGI scripts. Such browser based scripting tools run better on the computer of the reader. It is because such browser based technology use the local processor in the place of web server. Though the CGI scripts have some disadvantages, it is not advised you to discard it.
