It is said that IIS is not recommended for Comet programming. If that is true, how is it that other web servers are able to handle this vis a vis IIS. So what is it that oth
For some reason, this myth is still around. It's certainly possibly to do this with IIS, as demonstrated in our IIS-based comet server, WebSync.
The myth started with standard ASPX pages (which, if you hold open, will crap out around maybe 100 or so requests tops). It got better with async pages and handlers (which idle using much lower memory and virtually no CPU), and, with some clever working, can scale as well as, if not better than, many other comet solutions.
