Wildcard subdomains, block all other

I'm having a few issues with my new VPS just bought. I'm trying to configure Apache to accept wildcare subdomains on my main website, but allowing this also means that I can't block all others except the one created.

To be more explicit, I'm having this:

subdomain1.domain.com -> redirects correctly (CNAME added, folder ok, everything ok) subdomain2.domain.com -> same as subdomain1

subdomainN.domain.com -> the subdomainN doesn't exist. Thus, if I write "stackoverflowreallyrocks.domain.com" I'm being redirect to my stackoverflowreallyrocks.domain.com, with the content of domain.com - which isn't good.

Is there a way to redirect all subdomains that doesn't exists to domain.com?

The httpd.开发者_StackOverflow社区conf for the main domain is:

<VirtualHost *:80>
    DocumentRoot "/home/domain"
    ServerName www.domain.com
    ServerAlias domain.com
</Virtualhost>
<VirtualHost *:80>
    ServerName subdomain1.domain.com
    DocumentRoot "/home/domain/_subdomain1"
</VirtualHost>
<VirtualHost *:80>
    ServerName subdomain2.domain.com
    DocumentRoot "/home/domain/_domain2"
</VirtualHost>

Try adding another VirtualHost to the bottom of the config:

<VirtualHost *:80>
    ServerName *
    ServerAlias *
</Virtualhost>

The other VirtualHost entries should still match as they are better matches, and are prior to the wildcard host, allowing non-matching requests to fall into this last VirtualHost
