Sure, but you should use this to ONLY get the CGI parameters. Never ever put
your HTML page (Put_Line ("<HTML>"); ...) into the CGI... This mistake is
made often. The code and the design must be separated. This is why I have
build the Template_Parser package (simple but it has proved to be useful to
me).

What about AWS ? There is no program spawned, it is fast and very safe since
there is no spawned programs (the spawning mechanism is one common attack to
the Web servers).

Well AWS is all Ada :) and provides an Ada framework to build Web site.
