Cgi with Perl Online Training

Cgi with Perl Online Training



    CGI, or Common Gateway Interface, is the standard programming interface between Web servers and external programs. It is one of the most exciting and fun areas of programming today. The CGI standard lets Web browsers pass information to programs written in any language. If you want to create a lightning-fast search engine, then your CGI program will most likely be written in C or C++. However, most other applications can use Perl.


    • An understanding of standard HTML tags will be of benefit to a student.
    • A student does not need any previous experience of Perl or JavaScript.
