Salve,
ho un errore abbastanza insolito ... isi tratta di un upload di un file in cui ho settato la massima dimensione file ed estensione. In alcuni casi e random non funziona.

Se carico un fle sui 50 kb va sempre bene ma da quando si inizia a salire in dimensione dà problemi.

Con firefox 1.5 il risultato è il seguente

"The connection was reset

The connection to the server was reset while the page was loading.
* The site could be temporarily unavailable or too busy. Try again in a few
moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web."

strano perchè è lo stesso script che ho usato in precedenza sempre sullo stesso server e in quello di sviluppo funziona.

vi posto il codice

codice:
<?
///// CONFIGURAZIONE 
/////

$CfgMaxDimFile 			= 2000000; // 2Mb
$CfgMessageMaxDimFile 	= "Hai superato la dimensione consentita";
$CfgMessageNoFile 		= "Nessun File selezionato";
$CfgDirUpload 			= "/tmp";

ob_start();
session_start();

$ErrorDetect = "";

if ($_GET['invio'] == "invio") {
	if ($HTTP_POST_FILES['filename']['name']!= "") {
	
		$ErrorDetect = 0;
	
		$_SESSION['NameFileUser'] = "";
		$_SESSION['NameFileServer'] = "";
	
		if ($HTTP_POST_FILES['filename']['size']<$CfgMaxDimFile){
			if ($HTTP_POST_FILES['filename']['size']==0){ // se supero la dimensione massima del server nel php.ini
				$FinalErrorMessage = $CfgMessageMaxDimFile . " di " . $CfgMaxDimFile . " byte";
				$ErrorDetect = 1;		
			} else {	
				$FinalFileToServer = pathinfo($HTTP_POST_FILES['filename']['name']); 
				
				$ExtFinalFile = $FinalFileToServer["extension"];

					$FinalErrorMessage = $CfgMessageNoFile;
					$ErrorDetect = 1;			
				} else {
					$my_ip = explode(".",$HTTP_SERVER_VARS['REMOTE_ADDR']);
					$my_ip = $my_ip[0].$my_ip[1].$my_ip[2].$my_ip[3];
					$StringaNameFile = date("Ymd").date("His")."_".$my_ip.".".$ExtFinalFile; 
					@copy($HTTP_POST_FILES['filename']['tmp_name'], "$CfgDirUpload/$StringaNameFile") or die("Non è stato possibile effettuare l'upload del file ");
					$_SESSION['NameFileServer'] = "$CfgDirUpload/$StringaNameFile";
					$_SESSION['NameFileUser'] 	= $HTTP_POST_FILES['filename']['name'];
				}
			}
		}else{ // se supero la dimensione massima del che imposto nel config.php
			$FinalErrorMessage = $CfgMessageMaxDimFile . " di " . $CfgMaxDimFile . " byte";
			$ErrorDetect = 1;
		}		
	} else { // se la form è vuota
		 $FinalErrorMessage = $CfgMessageNoFile;
		 $ErrorDetect = 1;
	}


//print $FinalErrorMessage;
