php and xitami

[Ghirlandaio]

I've a problem with Xitami aliases.
For example, I have dreated an Alias named "pippo" for a directory
"C:\Server\Pipp o"
e.g.

[Alias]
pippo=C:\Server \pippo

The alias work, because when I navigate
"http://localhost/pippo"
the browser list the directory, but...
For experimental, I put in a simple php file
named "test.php":

<?
phpinfo();
?>

Well, when i navigate ""http://localhost/pippo/test.php"

nothing appear, but the error message
"No input file specified"
What is this?
Help please!
