使用无组件图文上传，如果获取大容量字段？

upload.htm中的代码如下：

处理页upload.asp代码：

<%
dim upload
set upload=new upload_F ''建立上传对象
Title=upload.form("title")
Text = upload.form("content")
……
%>

我在表单content里输入非常大的内容，然后处理的时候报错（输入的内容不多的时候可正常执行）：
错误类型：
Microsoft VBScript 运行时错误 (0x800A01C9)
此键已与该集合的一个元素关联
/manager/upload.inc, 第 58 行

使用普通表单提交的时候，我们一般都可以通过下面这样的代码进行处理：
For i = 1 To Request.Form("content").Count
Text = Text & Request.Form("content")(i)
Next
那么，在使用这样的无组件图文上传的时候，对这样的大容量字段如何处理阿。

附upload.inc代码：
<SCRIPT RUNAT=SERVER LANGUAGE=VBSCRIPT>
