That probably won't work, because the loaded operating system doesn't 
understand the concept of an HTTP SAN device.

You can boot a live Fedora from HTTP with a syntax such as:

   #!ipxe
   set repo http://server/path/to/distro
   kernel ${repo}/images/pxeboot/vmlinuz \
      initrd=initrd.img \
      root=live:${repo}/LiveOS/squashfs.img
   initrd ${repo}/images/pxeboot/initrd.img
   boot

This doesn't actually use HTTP SAN booting: instead you load the 
kernel+initrd directly and passing a kernel command-line argument which 
tells the initrd where to find the rest of the distro.
