'// ASPFileUpload.File API
'//
'// Properties
'// FileName
'// - Read/Write
'// - The file will be saved with this file name.
'// - This property can only be set before calling Upload.
'// - If no value is specified, the original file name
'// - in the HTTP post will be used.
'//
'// OverWrite
'// - Read/Write
'// - This property can only be set before calling Upload.
'// - If set to false and if the destination file exists, an error
'// - is raised. The default value is False.
'//
'// Target
'// - Read/Write
'// - The file will be written to this folder.
'// - This property can only be set before calling Upload.
'// - There is no default value for this property and it is required.
'//
'// Form
'// - ReadOnly
'// - Scripting.Dictionary object
'// - Can access a specific item by using aspfileupload.Form("item").
'// - Acts like the asp form collection.
'// - Can enumerate all values in a collection with for each.
'// - Only filled after the Upload method is called.
'//
'// Methods
'// Upload
'// - This method parses the HTTP Post and writes the file.
'//
'// Other
'// - ASPFileUpload requires COM+
'// - Any call to the Request.Form() collection will cause the Upload
'// method to fail as the method references the Binary contents of the
'// Request object through the Request.BinaryRead method.
'// - Also, if you access a variable in the Request collection without
'// specifying the subcollection that it belongs to, the Request.Form collection
'// may be searched. This causes an error in the Upload method.
