CGI Scripts

CGI Scripts is Programming language is created by the programmer and used for the Common Gateway Interface


CGI (Common Gateway Interface) is a form of interactive relationship where the client (browser) can submit an entry to the server, and server process inputs and return it to the client (browser). Simple example is when you use a search engine. Simple example is when you use a search engine. When you enter a keyword and press the Search button the browser will send the keyword to the server. When you enter a keyword and press the Search button the browser will send the keyword to the server. Keyword and processed by the server and the server sends the data processing results (according to the keywords that we enter) to our browser. Keyword and processed by the server and the server sends the data processing results (according to the keywords that we enter) to our browser. So we see in the browser only the appropriate data with which we enter the keyword. So we see in the browser only the appropriate data with which we enter the keyword.


To use the CGI server is the first condition with the UNIX operating system (and its variantnya). To use the CGI server is the first condition with the UNIX operating system (and its variantnya). But you need to note that not all UNIX server (I free) and capable of handling the CGI. Servers that serve as free web placement and GeoCities Homepage, the placement does not allow CGI scripts in our web. For that you can try Virtual Avenue, Tripod, or Hypermart (full list you can see here). But you need to note that not all UNIX server (I free) and capable of handling the CGI.

CGI programs are written in a language understandable by the system such as C / C + +, Fortran, Perl, tcl, Visual Basic, and others. CGI programs are written in a language understandable by the system such as C / C + +, Fortran, Perl, tcl, Visual Basic, and others. Elections language used depends on the system used. Elections language used depends on the system used. If we use programming languages such as C or Fortran programs so that we must make dikompile before running on the server so that there will be program source code and compile the results. If we use programming languages such as C or Fortran programs so that we must make dikompile before running on the server so that there will be program source code and compile the results. If we use different language scripts such as PERL, tcl, or Unix Shell then there is only akan script itself (without any source code). Many people prefer to choose to use CGI script compared with the programming language because it is easier to debug and in-modified. In this discussion we will use the Perl script as its language.
