This sounds a bit more promising, thanks. I'll be sure to explore this. One thing bothers me a bit though:

From the CGI.pm documentation, Server Push section:

Users interested in server push applications should also have a look at the CGI::Push module.

Only Netscape Navigator supports server push. Internet Explorer browsers do not.

Is this what you were referring to? I've also heard some rumblings that this is highly dependent on the server from which the script is served. Any truth to this? Does IE now work properly? The environment in which my code will be used sees a very wide audience and frequent changes in both browser and server software.
