in thread How to replace the output (new html page)?
As the other Anon hinted at, server push technology (originally introduced by Netscape -- yes, it's that old) appears not to work in MSIE, but the other major browsers seem to handle it fine.
An alternative solution would be to save your second HTML page (temporarily?) to a publicly-accessible place, and redirect/link there once you are done. Some strategically placed output flushing might work best there (but might also be broken by a change of your web server or CGI serving configuration).
