When linking documents in IE, if it encounters a document supported by OLE, IE will automatically call the corresponding program to open it. Sometimes this function is not what we need, although we can remind the user to right-click the mouse-->save target as ....command to download documents, but this is not very friendly after all. This article describes the use of FSO and Stream methods to implement direct downloading of documents by IE. <%@ language=vbscript codepage=65001%>
