Normaly (never tried http install), it should be like:
  grub> linux ks=http://.../ks.cfg [ method=http://.../ ]
And, in ks.cfg:
  url --url http://.../

>From the doc (http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Installation_Guide/ch-kickstart2.html):
"If you are performing a network-based (NFS, FTP, or HTTP) installation, you must make the installation tree available"
"An installation tree is a copy of the binary Red Hat Enterprise Linux CD-ROMs with the same directory structure."
Which would mean no ISO files...
