Hi Scott,

    Sorry for my disturb but I can't resolve one my problem and I have seen that you work to it. I must use Excel RTD Function to get data updates in real time. This function uses callback and I want that the server with the real time data source stays behind a firewall. I tried to use CIS but the callback open a new connection that uses port 80 only if on the client runs IIS. There is a way to permitt the callback to use the same connection opened by excel with the RTD function?

    I think no... the RTD Server is a DLL registered on both server and client. Which protocol can I use to permitt the 2 same dll to communicate over http 80? Perhaps I must use SOAP? I must mjodify my dll code to use it?

Thanks!!!!
