I'm trying to set up multiple domains on my Amazon EC2 micro instance running Ubuntu Server 12.04. I installed Apache correctly and set up virtual hosts but having problems with wildcard subdomains.

This is what my httpd.conf file looks like

NameVirtualHost *:80

<VirtualHost *:80>
    UseCanonicalName Off
    VirtualDocumentRoot /home/username/domains/%0/html/
</VirtualHost>

My DNS records (on Amazon Route 53) are:

domain.tld      A    1.2.3.4
*.domain.tld    A    1.2.3.4

If i create a test.domain.tld directory with the html subdirectory, it works fine. But what I want to do is to redirect *.domain.tld to domain.tld in case there is no directory for the sub-domain accessed. I would also like www.domain.tld to redirect to domain.tld. The system should also work if I decide to host another website, example.com, on the server.

I tried Googling a lot but without any luck. Suggestions?
