Identification
-
Files with CGI extensions are normally located on a Web server in a special directory named "cgi-bin," although they may be hidden for security purposes.
Benefits
-
CGI scripts offer an easy way to send information on HTML (Web) forms to an email address or file. They also allow dynamic interaction with Web pages rather than simple static pages.
-
Considerations
-
CGI contact forms, particularly unsophisticated ones, offer hackers an opportunity to break into a server and take over permissions about how files execute as well as hijacking email accounts.
Features
-
The Common Gateway Interface is actually a type of programming language with specific commands such as "Get" and "Post" that direct how content on a form is used.
Warning
-
CGI programs on a server or personal computer are executable by anyone so it is important to use security settings controlling access.
