standard, release version of ColdFusion 3.1.1 in this manner. To do so, it was necessary
to purchase and install special versions of the ColdFusion Web server plug-in modules
on the Web server side and a separate listener module on the ColdFusion engine side.
In ColdFusion 4.0 all the necessary pieces are provided as part of the standard
distribution. All the supported Web server plug-ins have been enhanced to include the
capability to send and receive ColdFusion data via TCP/IP, and the engine-side listener
module is available as part of the standard release.
Configuring Distributed ColdFusion
Before trying to run ColdFusion in a distributed configuration, you must perform a
standard installation of ColdFusion on all the machines involved. On the computer
running the Web server, this guarantees that the ColdFusion server plug-ins are
correctly loaded by the Web server. On the computer running the ColdFusion engine,
this guarantees that the engine is set up and operating correctly.
Having complete, standard installations of ColdFusion available on all machines also
provides a useful baseline environment so that validation can be done in the absence
of the remote extensions. Should problems arise using ColdFusion in remote mode, it‘s
possible to run ColdFusion locally to determine whether or not the problems are
related to the distributed configuration.
If, after successfully testing your remote configuration, you wish, for security reasons,
to disable the ColdFusion engine installed on the computer hosting the Web server,
you can do this easily by renaming the following executable files in the
cfusion/bin
(Windows) coldfusion/bin (Solaris) directory:
•
cfserver
•
cfrdsservice
•
cfexec
This prevents any ColdFusion server-side process from running while generally
preserving your ColdFusion configuration.
Using the modified plug-in
In ColdFusion 4.5 all the Web server plug-ins are remote-capable so no special
installation is required. All you need to do is let the plug-in know that you want to run
in remote mode. You do this by putting the following information in an INI file and
putting that file in the root directory of your ColdFusion installation on the machine
running the Web server. That INI file must be named
cfremote.ini . To enhance
security, this INI file may be optionally set to be automatically deleted after being read
at startup.
