A CGI script needs to output a MIME header. At a bare minimum, you need to
add the following:
print "Content-Type: text/plain\r\n\r\n",
"ciao\n";
There are two \r\n pairs there because the header must end with a blank
line.
To do this with the CGI module (recommended), use:
#!/usr/bin/perl -w
use CGI ':standard';
print header('text/plain'),
"ciao\n";
If you want to output HTML instead of plain text, do something like this:
#!/usr/bin/perl -w
use CGI ':standard';
print header,
start_html('Ciao'),
p('ciao'),
end_html;
