<%option explicit%>
<%Response.Buffer = True%>
<%
    ' Declare objects and variables.
    Dim strPath, strContent, strUserName, publickey, privatekey
    Dim objDownloadMgr, objHeader, strHeader

    ' Retrieve end user and file information from the form.
    strPath = Request.QueryString("path")
    strContent = Request.QueryString("content")
    strUserName= Request.QueryString("username")
 
    ' Create a download manager object.
    Set objDownloadMgr = 
       Server.CreateObject("wmrmobjs.reheader") 

    ' Create a header object.
    Set objHeader = Server.CreateObject("Wmrmobjs.WMRMHeader")
        ' Place header information into the header object.
    
    strHeader = objDownloadMgr.GetDRMHeader(strPath+"\"+strContent)
    objHeader.Header = strHeader
    objHeader.Attribute("UserName") = strUserName
    privatekey = "XXX"    ' XXX is the packaging server's private key.
    objHeader.Sign(privatekey)
    strHeader = objHeader.Header

    ' Add the header to the Response object.
    Response.AddHeader "Content-Disposition", _
                       "attachment;filename="+strContent

    ' Force the end user to download the packaged file.
