Customized fallbak page

[Gustavo Mateus]

Hi,

I have 10 virtual servers (http) running on one director with 5 real 
servers and a separated fallback server running lighttpd.

I want to customize a fallback server page for each of the 10 web sites 
running on the virtual servers.
The way I imagine it can be done is setting lighttpd to respond to 10 
different ips. One ip on the fallback server for every virtual server 
that I have.

Is there a way to avoid that? I dont know, some way to use virtual hosts 
and use just one IP for fallback server?

Thanks

Gustavo
