[users@httpd] Réf. : Re: [users@httpd] NameVirtualHostDefaults

[Antoine PICOLET <an...@sagem.com>]

A _default_ virtual host is never used for NameVirtualHosts. If you 
declare something like :

NameVirtualHost 192.168.0.100:80

<VirtualHost 192.168.0.100:80>
ServerName a.site.com
[... snip ...]
</VirtualHost>

<VirtualHost 192.168.0.100:80>
ServerName b.site.com
[... snip ...]
</VirtualHost>


then the 'default' Virtual Host is the first of the list (a.site.com). 
_default_ virtual hosts are only used with IP-based vhosting, such as :

Listen *:90

<VirtualHost 1.1.1.1:90>
ServerName a.site.com
[... snip ...]
</VirtualHost>

<VirtualHost 2.2.2.2:90>
ServerName a.site.com
[... snip ...]
</VirtualHost>

<VirtualHost _default_:90>
ServerName default.site.com
[... snip ...]
</VirtualHost>

In tom's case, using Name Virtual Hosts, specifying a default Virtual 
Host, mapped to any request not covered by others, is as simple as 
specifying it as the first in the list. I personnaly use a 'fake' Virtual 
Host, rejecting everyone, as the first, which looks like that:

<VirtualHost 192.168.0.100:80>
ServerName site.com
<Directory "/">
deny from all
</Directory>
</VirtualHost>

 From my understanding of the _default_ it will caught unmatched IP 
addresses

Example:

<VirtualHost 192.168.0.100:80>
ServerName a.site.com
[... snip ...]
</VirtualHost>

<VirtualHost 192.168.0.100:80>
ServerName b.site.com
[... snip ...]
</VirtualHost>

<VirtualHost _default_:80>
[... snip ...]
</VirtualHost>

If the domain name with IP address 192.168.0.101 came into the server it 
will use the _default_ vhost.

But if c.site.com with IP address 192.168.0.100 came in it would use the 
first vhost with IP address 192.168.0.100. Which is a.site.com

I am not 100% sure this is how it work as I have not tested this out. 
But I think this is what happens.

Mark.
