1. Re: How to not run a gateway instance if the target server is down
The DirectoryWatcher gateway is designed to check a directory on the same server, not on another server.

2. Re: How to not run a gateway instance if the target server is down
It works fine on other servers as long as permissions are set correctly. -
3. Re: How to not run a gateway instance if the target server is down
How do I tell the gateway instance to not run if the server it is looking at is down or the directory in this case is unavailable?
I missed that one. Coldfusion's gateways are perpetual listeners, threads that are designed to run continuously.

4. Re: How to not run a gateway instance if the target server is down
listeners have a timeout period. if the target computer is going through a reboot cycle, the downtime should be short enough that you can setup a timeout. Set one that is long enough so that you do not trigger a failure event, and the timepsan allows for the target server to come back online before the timeout expiration.
Another way that is more robust is to create a seperate application, perhaps one built on Visual Studio or even a scripthost that does a simple ping of the destination server every 10 seconds or so. When the server is not found, you can do a shutdown of your CF. (you can shutdown any application from another application). Once you can re-ping the server, relaunch your gateway listener. If the listener cannot support what you want to do, just write another program that will perform your logic for you.
