standard error page per virtual host

Hi there!

I'm new to mathopd but I thought it could serve all my wishes.

The question is: Does mathopd support setting standard error pages?

I have a small energy saving webserver that still runs when all other webservers are shut down due to power out. This server is backuped by an ups.
It will be configured to take over the ip addresses of the shut down webservers and should serve a single static webpage for each virtual host configuration.

The question is can mathopd redirect all requests to a single html file?

e.g.

http://abc.domain.org/xyz/file.html 
should not generate a 404 error page but reply the standard file:
/srv/www/abc.domain.org/index.html

And so for _all_other_ URLs under abc.domain.org
So it's a kind of universal redirect.

If you don't understand what I mean just ask. English is not my mother tongue.

Best regards
Lars
