Help configuring adobe media server's apache to use UNC paths and use multible VOD directories

I am experimenting with v 5.03 for media server with look to upgrade our current pool of v4.x server to support ipads etc.

i have set the ams conf file and have in the past use a unc paths for my VOD_Dirs

eg

VOD_DIR = C:\Program Files\Adobe\Adobe Media Server 5\applications\vod\media

VOD_DIR_1 = \\prodserver1\media\data\VOD\Media

VOD_DIR_2 = \\prodserver2\media\library\Preview

VOD_DIR_3 = \\prodserver3\media\preview

how and where do i need to do this for the http streaming ?
