salve a tutti.
sto imparando a usare le sessioni e subito mi trovo davanti un problema...

da una semplice pagina html:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<?php session_start(); ?>
<title>*Prova*</title>
</head>

<body>
Ciao
</body>

</html

il browser segnala
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at main.php:4) in main.php on line 4

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at main.php:4) in main.php on line 4
Ciao

Sapete aiutarmi?
Grazie!
