One ip on port 80 with mutiable vhost different names and ports

Question

I'm unsure of how to ask or describe in words what I'm trying to do, or if it can be done this way, so I decided to draw a diagram. Hopefully its fairly self explanatory:

I know I can do Named based virtual hosts all on Port 80, but can I place them on different ports and have the server work out what named host is which and which port they are on?

<VirtualHost _default_:80>
    ServerAdmin webmaster@localhost

    DocumentRoot /var/www/foo-1.com
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /var/www/foo-1.com/>
        Options -Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

<VirtualHost _default_:80>
    DocumentRoot /var/www/foo-2.com
    ServerName foo-2.com
    <Directory "/var/www/foo-2.com">
        allow from all
        Options -Indexes
    </Directory>
</VirtualHost>

Answer 1

To have two name based virtual hosts working on the same IP address try something like this

NameVirtualHost *:80

<VirtualHost _*:80>
    ServerAdmin webmaster@localhost
    ServerName foo-1.com
    ServerAlias www.foo1.com
    DocumentRoot /var/www/foo-1.com
    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /var/www/foo-1.com/>
        Options -Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot /var/www/foo-2.com
    ServerName foo-2.com
    ServerAlias www.foo-2.com
    <Directory "/var/www/foo-2.com">
        allow from all
        Options -Indexes
    </Directory>
</VirtualHost>

Note that each vhost has a ServerName and ServerAlias

On first reading your scenario, my first response was why would you want to do it this way much like the others, but with Apache or PHP something like this is possible. You would be much better off getting virtual hosts to work properly on port 80 as this is what web site visitors expect, but this is my opinion.

To do what you'd like to accomplish, there are two options and you have to be comfortable that an HTTP redirect has to happen. No way around that one.

Your first option is to use PHP for this with something as follows...

1. Your main Apache site would cover all default site requests using PHP
2. PHP would read the headers, look at the URL and pass back a redirect to the browser
3. The browser would then redirect to the correct URL

Apache supports a rewrite option as well and you could organize this for each site in the following manner

# First host rewrite
RewriteCond %{HTTP_HOST} ^www.\foo-1\.com$ [NC]
RewriteRule ^(.*)$ http://www.foo-1.com:8080/$1 [L,R=301]

# Second host rewrite
RewriteCond %{HTTP_HOST} ^www.\foo-2\.com$ [NC]
RewriteRule ^(.*)$ http://www.foo-2.com:8081/$1 [L,R=301]

However, if you are going to go to this level with rewrite conditions, it may be easier to figure out VHOSTS in Apache and get it working properly on your server.
