I guess the above answer is technically correct, although I would never use Server Push technologies. From the small experiments that I have run with Push (about a year ago), I noticed that while the server-side works well under Apache, MS browsers tend to hang if you leave them running on push for over long periods of time/data.

On the server-side, my first try was with ActiveState and IIS 4.0. Needless to say that for every open connection another perl process spawned and soon enough the machine was brought down to its knees. I guess it was probably something that I was doing wrong, but I managed to improove this greatly by moving everything to a Linux server running everything under Apache.

IMHO, too many small glitches to actually do anything serious.

I fooled around a bit with Active Channels (remember that screensaver thingy that came with IE 4.0?) trying to build a newscast for my intranet with perl. It didn't work out as I had expected. I'll try and find the code I was working on (if I still have it on tape).
