Hi Erik, Ronald, et. al
PFMJI,
Its been a while since I looked at this, but there is a MIME type that allows server push via a CGI (and I am guessing ASP) script.
The MIME type is multipart/x-mixed-replace
How it works is you send the page with this in the header (HTTP header, server side) and a Programmer-defined boundary string, and it keeps the pipe open. Then your script can periodically send refresh data, followed by the boundary string, until the pipe is closed.
Its true push, but its (was, I haven't looked at this in about 3.5 years) a little tricky to implement, and the server needs to be set up to handle it.
I read about it in CGI Programming on the World Wide Web (Nutshell Handbook)

I also found this link, but the above is probably better:
