You may also wish to consider running the http daemon under xinetd, 4.4BSD
inetd, or binetd.  All three of them permit control over the number of
daemon spawns per time-unit (second/minute).  Xinetd and binetd also have
built-in host and domain access control rules.  
Xinetd is archived at the COAST Security Archive accessible at:
ftp://coast.cs.purdue.edu/pub/tools/unix/xinetd
Binetd can be found at:
ftp://ftp.engarde.com/pub
