A bit back Brian Szoszorek showed a wonderful example on how to use Cold Fusion's gateway functionality to help streamline the use of the Trusted Cache. This article was brought to my attention by a fellow co-worker and after reviewing the article in detail I was stunned on how powerful this was and how easy it was to implement. So I decided to tweak it here and there to see what else it could do.

In the end 90% remained the same. The only tweaks that I made was to enable to clear caching method to be just a little smarter by just removing specific files from the cache rather than the entire cache itself. I've also added a new method called "setEventGateway" which creates the needed cfg file and gateway entry within Cold Fusion Administrator giving the ability to build these necessary gateways on the fly. Very Cool.. Very Powerful.. and Very Easy!

You can download the code here.

Here are the steps on how to implement:

1)       Create a new directory that the component will live in and place the component in there

a.       Example: C:\inetpub\wwwroot\clearCache

2)       Access and run the setEventGateway method provided within the component and provide it the directory you want to watch

a.       Example: #createObject("component", "templateListener").setEventGateway(directoryToWatch="c:/inetpub/wwwroot")#

3)       Turn on Template Caching within Cold Fusion Administrator by (CF Admin -> Server Settings -> Caching -> Trusted Cache)

4)       Confirm that the Gateway Instance is running by (CF Admin -> Event Gateways -> Gateway Instances)

5)       That's it
