Prevent apache serving anything other than domains

[slayer1ss]

Hi, sorry to bother you guys... When i use Apache's mod_status extension i see the connections that are made to my server, almost %40 of these connections are actually connections to the domains that server is hosting however %60 these connections are like below, is there a way of preventing these even getting to apache? Would preventing these give me more performance?

Srv PID Acc M CPU SS Req Conn Child Slot Client VHost Request
1-0 16559 0/21/164 _ 0.39 3 8 0.0 0.86 4.59 212.156.209.132 default-185_86_15_201:443 NULL
7-0 - 0/0/105 . 0.24 0 0 0.0 0.00 2.16 ::1 ns.century21.com.tr:80 OPTIONS * HTTP/1.0

This is beyond annoying..

we had one client who had hundreds of identical clones of his site. The urls were in the form of

http://something.com/random.php?actual.domain.com/some_page

after going around in cirlces we found the best fix was to add

## Deny illegal Host headers
if ($host !~* ^(realdomain.nl|www.realdomain2.nl|real_alias.nl|www.readldomain.nl)$ ) {
return 444;
}

to the top of the Server{
block in nginx vhost conf file

Hi, first of all thank you for the response... I am not using nginx do you think this will work with apache's httpd.conf ??

There are a range of .htaccess fixes for this but none worked as well as the above.. nginx is pretty low profile... switch it on and give it a go.
