下面将介绍一系列可以不用组件，而使用纯粹的ASP代码来上传文件
呵呵，我想这将给很多拥有个人主页的网友带来极大的方便。
    这个纯ASP代码由三个包含文件组成，代码中只使用了FileSystemObject
和Direction两个ASP固有对象。而不需要任何附加的组件，注意，为了保证
这段代码的出处，我没有对代码中的任何地方进行过修改。
    希望能够对大家有所帮助：

'Sample multiple binary files upload via ASP - upload include
'c1997-1999 Antonin Foller, PSTRUH Software, http://www.pstruh.cz
'The file is part of ScriptUtilities library
'The file enables http upload to ASP without any components.
'But there is a small problem - ASP does not allow save binary data to the disk.
' So you can use the upload for :
' 1. Upload small text (or HTML) files to server-side disk (Save the data by filesystem object)
' 2. Upload binary/text files of any size to server-side database (RS("BinField") = Upload("FormField").Value


'Limit of upload size

'This function reads all form fields from binary input and returns it as a dictionary object.
'The dictionary object containing form fields. Each form field is represented by six values :
'.Name name of the form field (<Input Name="..." Type="File,...">)
'.ContentDisposition = Content-Disposition of the form field
'.FileName = Source file name for <input type=file>
'.ContentType = Content-Type for <input type=file>
'.Value = Binary value of the source field.
'.Length = Len of the binary data field
