We have been running Apache with CF 4.5 on NT 4 for the last 2 year under
very heavy load and have found no stability problems that were related to
Apache. Additionally, because of the open API of apache we have been able
to do some very interesting things for scale and reliability:
1. Run 2 instances of apache on each web server. One handles all CF
requests and one handles all static requests (images mostly). We have found
that apache can serve over 500 14K files per second on a dual PIII 600 (we
were actually bottlenecked by the 100mb network. With 1K files we hit about
750/sec). Running 2 instances of apache allows us to have cold fusion under
load and not slow down the delivery of all the images required to complete
the page.
2. Create modules to handle high load. We build pages in CF, then if the
page is seeing more load than CF can handle, we write an apache module in
C++ to handle that one function and use the Apache handler to intercept the
..cfm request, check if we have a custom handler for the page, handle it if
we do, and pass it on to CF if we do not. This is, BTW how we are able to
set cookies during a server side redirect.
3. Bind different virtual hosts to different ports (I do not use IIS so I do
not know if yuo can do this or not). Our webserver has a single IP and each
host is a different high port (8080, 8081,8082, etc). We handle the
redirection from different external IP's to a single Internal IP, different
port either in the firewall or the load balancer. This allows the
adding/removing of hosts without re-ip'ing the web server and limits the
number of IP addresses which is important for some firewall licensing
schemes.
We are firm believers in the KISS principle (keep it simple stupid). Apache
is pretty simple, we upgrade when we want to, and it does not try to hook
into too many OS functions that may cause issues.
The down side is that it requires a programmer to make the most of it and
the interface is config file based, which not everyone is comfortable with.

Well I think this is one of those YMMV moments. I ran Apache, CF 4.5 and
mySQL on an NT4 server for months with no problems at all. And it was, YMMV
again, more stable than when I was running IIS.
