Request.BinaryRead methoddata= Request.BinaryRead(bytes)
This method is used when the client sends binary data to the server, for example, as a part of a file upload form input.
The data returned by this method is pretty difficult to work with using VBScript or JScript; it needs to be broken apart, decoded, etc. Using a third-party component, like the ASPFileForm, to read the fields from a file upload is advisable.
