I'm not sure what you mean by 'server push' but if you want to update a 
web page progressively, you have to make sure that your web server isn't 
buffering. I think IIS does buffer by default.

You can then send out incremental updates to the page using print from a 
CGI script. Bear in mind though that the web page must suite this type of 
update. Also, some browsers might not display it correctly until they 
have the </html> tag.
