There is some debate as to whether CGI is obsolete because this functionality can also be provided by using JavaScript and new Web programming tools like PHP. While some aspects of Web design are moving away from the use of CGI and the CGI-bin, some designers still like to use this kind of system to add dynamic features to a Web page. Still, there are some drawbacks to using a CGI approach related to the individual commands needed to load scripts. There can also be issues with browsers timing out as a result of faulty script.
