Hi AndrÃš,
thanks for your help.
The code I have written is the follow:

*#touch.pm
   use strict;
   use warnings;

   use Apache2::ServerUtil ();
   use Apache2::RequestIO ();

   sub handler{
       my $r = shift;
       $r->content_type('text/plain');
       $r->print("<html><body><h1>ciao mondo</h1</body></html>");
    }
    1;*

When I access to http://localhost:81/ on my Apache server, i have a 
white page and the *error_log* file contains:

<b>Warning</b>:  PHP Startup: Unable to load dynamic library 
'ext/msql.so' - ext/msql.so: cannot open shared object file: No such 
file or directory in <b>Unknown</b> on line <b>0</b><br />
failed to resolve handler touch

What's the matter?
I don't understand what is the problem!!

Any suggests is appreciated.
