HMLHttp.SetTimeouts

I am trying to send race results to race finishers in classic asp and my script keeps timing out.  I have my Server.ScriptTimeOut set plenty high.  (note that I just added the xmlhttp.SetTimeOuts)  Not sure if I have the other timeout set correctly.  Can someone look at the following code and let me know what changes might help please?  Thans!

Set cdoConfig = CreateObject("CDO.Configuration")
With cdoConfig.Fields
    .Item(cdoSendUsingMethod) = cdoSendUsingPort
    .Item(cdoSMTPServer) = "smtp.mandrillapp.com"
    .Item(cdoSMTPAuthenticate) = 1
    .Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 587
    .Item("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = cdoBasic
    .Item(cdoSendUsername) = "username"
    .Item(cdoSendPassword) = "pwd"
    .Update
End With

    bSentBCC = False

	For j = 0 To UBound(SendTo) - 1
		'get email address
		sMyEmail = vbNullString
				
		If DontSend(SendTo(j)) = False Then sMyEmail = SendTo(j)

		If Not sMyEmail = vbNullString Then
			If ValidEmail(sMyEmail) = True Then
                            
                sPageToSend = "http://www.gopherstateevents.com/misc/pix-vids_notif.asp?event_id=" & lEventID 

                Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")
	                xmlhttp.open "GET", sPageToSend, false
                    xmlHttp.SetTimeouts 0, 60000, 300000, 300000
	                xmlhttp.send ""
	                EmailContents = xmlhttp.responseText
                Set xmlhttp = nothing

			    Set cdoMessage = CreateObject("CDO.Message")
			    With cdoMessage
				    Set .Configuration = cdoConfig
    				    .To = sMyEmail
				    .From = "bob.schneider@gopherstateevents.com"
                   		    .Subject = "Pictures Are Ready for " & sEventName
				    .HTMLBody = EmailContents
				    .Send
			    End With
			    Set cdoMessage = Nothing
		    End If
        End If
	Next

    Set cdoConfig = Nothing
