Apache2 VirtualHost redirects

[Keldorn]

I have got small web server with several web sites on it.
When I am adding new dns record - and going to www.my_new_website dot com (There is no virtual host for it), Apache redirects me on my first virtual host. How to make it send 404 error for websites if there is no virtual host for it?

Looks like named based here.
http://httpd.apache.org/docs/2.2/vhosts/name-based.html

Don't see any options for it.

I see this in /etc/httpd/conf/httpd.conf

# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
