Ya, I use it over http as well.

In kickstart; use:
url --url=http://192.168.1.254/c5/x86_64/img/

In the PXE config file, the matching entry would be something like:

LABEL c5_an-node01
        MENU LABEL ^1) Install AN!Node01; Storage Node 01 - Cluster 2
        KERNEL boot/c5/x86_64/vmlinuz
        APPEND initrd=boot/c5/x86_64/initrd.img
ks=http://192.168.1.254/c5/x86_64/ks/an-node01.ks ksdevice=eth1
