Input Processing

A great deal of CGI processing involves capturing the contents of HTML forms as presented to the standard input stream, then reformatting them, decoding the HTML, reading environment variables, and so on. Because this is one of the most tedious aspects of developing CGI applications, many developers use third-party libraries and tools, such as the Perl utilities Cgi.pm or Cgi-lib.pl. In most cases, these utilities are unnecessary in ASP applications because the ASP environment takes care of most of these housekeeping tasks for you, as described in the following topics:
