I was wondering if there was a way to set up 2 "redundant" web servers
(identical web sites), i.e. when one crashes, the other one takes the
connection over. The same thing which is already available for
firewalls(high disponibility), but with web servers.

We would have 2 Windozes in a DMZ with IIS as the web server, and a
pix firewall between the dmz and Internet. Is there any tool allowing
this out there ? I tried to google quite a while, but without any
chance...

Lots of:
- Cisco Load Balancer (or Alteon or F5 or ...), expensive
- reverse Proxy in between Pix and servers
- DNS RoundRobin (and checks on the DNS server)
- Linux Virtual Server - with ICMP redirect
- STONITH type of scripting on the IIS systems, taking over
  the IP address of the broken system
