Multiple interfaces required to run multiple Apache web servers?
I've noticed that some webservers have sub-interfaces with different IPs, so that they can serve up different web sites.
For example, a single box running Solaris 8 might have it's primary interface (hme0) be 10.1.1.10 and web.domain.com in DNS, and a subinterface of hme0:1 be 10.1.1.11 and web2.domain.com in DNS.
They do that so that when you browse to http://web or http://web2 you get different sites, but both served by Apache on the same box..
Isn't it possible in Apache to use a single IP, and direct to different websites based on the DNS name someone uses?
For example Apache would say
http://web.domain.com --> /index.html
http://web2.domain.com --> /directory/index.html

Yes, this is called Virtual Hosting... Hold on a minute and I'll point you to the doc.
Here's the document:
http://httpd.apache.org/docs/vhosts/
It's very easy to set up. For instance, here's an example:
<VirtualHost 123.123.123.123>
ServerName foo.bar.com # This is the DNS name you want to associate
DocumentRoot /baz/httpd
<Directory>
# some directory stuff here that applies to this virtual host.
</Directory>
</VirtualHost>

Thanks. I'd also appreciate any pros/cons of doing it with one IP vs multiple IPs, assuming you are running on the same physical box?
