This class can be used to write programs intended to be the targets of web server forms.
This library parses standard input and the environment variable QUERY_STRING for variables from a from submitted to a webserver.
Standard input is parsed first, followed by the QUERY_STRING. This allows a form variable to be overridden by specifying it in the URL. Query string processing can be suppressed by calling make_no_query_string instead of make. The CGI variables can be retrieved by using the cgi_vars associative array, or by using various query methods.
A cgi variable can (rarely) have more than one value. Probably the most likely occurance of this would be with a selection box that allows multiple selections. Some of the query functions ignore the possibility of multiple values, and only operate or return the first value. However, a query method is provided for those instances where there may be multiple values.
