ColdFusion gateways arranges images and files in templates and thumbnails by converting them into simple batch process. It is very hefty for a user to upload images through the HTTP requests because he has to wait for a long period of time.

For the directory gateway configuration file, there are following attributes required -

directory - path to the directory to watch.

recurse -  to check to the subdirectories.

addfunction - defines the name of function to be called.

ChangeFunction - defines the function of the file when it is updated.

interval - number of milliseconds between the event gateways.

deleteFunction - name of the functions, when the file is deleted.

extensions - comma delimited sets of the extensions.
