ABSTRACT

Common Gateway Interface

Package CGI is an Ada 95 interface to the Common Gateway Interface (CGI). This package makes it easier to create Ada programs that can be invoked by World-Wide-Web (WWW) HTTP servers using the standard CGI interface. Using it, you can create Ada programs that perform queries or other processing by request from a WWW user.

This package is copyright (C) 1995 David A. Wheeler (wheeler@ida.org). You are free to use it in anything you wish without restriction or payment, but please provide credit if you use this package.

This Ada package provides two data access approaches from the CGI:

• As an associative array; simply provide the key name (as a string) and the value associated with that key will be returned.
• As a sequence of key-value pairs, indexed from 1 to Argument_Count.

This access approach is similar to the Ada library Ada.Command_Line. The main access routines support both Ada 95 types String and Unbounded_String.
