Oh Wow!! Surprised!!! Great demonstration and works perfectly! And I just notice the `system()` or the backticks ( the right tool for my case ) are actually kind of fork thing... which is the "how" that I exactly asking! Thanks man! Though.. what still puzzle me is how do you leave the `<STDIN>` open for the CGI to `read()` in this code pattern ?	[reply] [d/l] [select]

Its not a pattern, just shows %ENV is inherited from parent process Its one part of what HTTP::Request::AsCGI does, STDIN... stuff is the other part	[reply]
