Prevent FMS3 from creating http directory under my application's directory

Question

I recently upgraded my environment from Flash Media Server 2to Flash Media Server 3, and I'm seeing a new behavior that's bugging me.

For some of my applications FMS is creating an "http" directory under the application's directory, and creating subdirectories within that for each application instance.

So, for an app called "myApp" stored at:

C:/FMS3/applications/myApp

FMS3 creates:

C:/FMS3/applications/myApp/http

and then creates a subfolder for every app instance:

C:/FMS3/applications/myApp/http/1
C:/FMS3/applications/myApp/http/2
C:/FMS3/applications/myApp/http/3

All the subdirectories are empty.

I've searched the FMS3 docs and I haven't found any mention of these directories. This is creating a lot of noise on the filesystem for no good reason. Is there any way to turn this off? Why is it doing this in the first place?
