Upload De Arquivos Grandes

omicron · Abril 19, 2005

galera, alguém aí conhece algum script de upload que suporte o envio de arquivos na faixa de 30 mb? eu já peguei uns dez scripts tanto de asp como php mas todos eles só suportaram arquivos com no máximo 1 mb e preciso que suporte os arquivos grandes, já alterei o Server.scriptTimeout pra 10000000000000000000000000 e nada......esse é o link: http://www.mag.eti.br/upload/upload.asp, mas de qualquer forma aí vão os scripts:

upload.asp

<html>
<head>
<title>Upload de fichier</title>
<script language="JavaScript"> 
<!-- 

function validar() {

var ext = new Array()
ext[0] = ".zip";

extensao = document.frmInserir.File1.value;
posicao = extensao.indexOf(".");
tamanho = extensao.length;
extensao = extensao.substring(posicao, tamanho);

valida = 0;
for (var i = 0; i < ext.length; ++i){
if (ext[i] == extensao){
valida = 1;
}
}

if ((document.frmInserir.File1.value != "") && (valida == 0 )){
alert("A extensão do Arquivo não é valida. Só serão aceitos Arquivos Compactados (.ZIP)");
document.frmInserir.File1.focus();
history.back();
} else {
frmInserir.submit()
}
}
//-->

bom, e o erro apresentado foi:

Request object error 'ASP 0104 : 80004005'
Operation not Allowed
/upload/upload.inc, line 48

se alguém puder me ajudar serei grato pois estou precisando urgente.....

tipo assim esse upload sem componentes é meio estranho ... porque mais de 450 kb ele já da erro (pelo menos quando tentei usar foi assim)... o que você deve fazer é verificar qual componente possui no seu server....

ai você posta aqui... mais a ideia é a seguinte:

- o arquivo é grande... então o timeout tem qu dmorar pra acontecer..

- e o tamanho do arquivo.... pode ser definido um maximo .... mais pra cada componente é uma maneira....
