My understanding was that Apache for NT used the POSIX subsystem, and took somewhat of
a performance hit because of it. Is this not the case?

I was running Apache on my development machine for local testing. It was
rather under-horsepowered for running as a CF server. But it ran better
than PWS on NT 4.0 Workstation.

How did you configure this? Did the different instances have different
ports?

Nice idea. I'm hoping the CFFLUSH tag will allow this to happen under IIS.
If not, I am going to suggest that we switch to Apache and try something
similar. I guess the module set the cookie and then let the CF server
process the cfm page.

IIS has a variety of tools. You can set it either to answer on a specific
IP address on multi-homed systems. When you set the IP address, you also
can set the port that the web site (Virtual Server) answers. Though I have
never tried it, I am told that you can even have IIS differentiate to
different Virtual Servers answering on the same IP address and port based
upon the domain name in the header. I don't think that is particularly
efficient when it is pretty easy to either multi-home a NIC or have multiple
NICs depending on bandwidth requirements.

True, but we chose to use IIS since we all (the CF developers) knew how to
administer it. Only I knew how to administer Apache.

Being on old SunOS (NOT Solaris) gearhead I can appreciate it. I still
prefer to tweak my Win 2K box by editing the Win.ini file.

Thanks for sharing it. It gave me a few ideas to file away and suprise the
CTO with. ;)
