I've been struggling with this, basically what I want is this:

A virtual domain to run on the 80 another virtual domain to run FROM 80 TO 8080

what I've done so far is trying different combinations with apache, but all i got is having all the virtual domains pointing to port 80 this is my conf:

<VirtualHost domain1.com:80>
DocumentRoot /var/www/domain1
<Directory "/var/www/domain1">
allow from all
Options +Indexes
</Directory>
ServerName domain1.com
</VirtualHost>

<VirtualHost server.domain2.com:80>
DocumentRoot /var/www
<Directory "/var/www">
allow from all
Options +Indexes
</Directory>

    ServerName server.domain2.com
    ServerAlias www.server.domain2.com
    ProxyPass / http://server.domain2.com:8080/

       </VirtualHost>

suggestions? :(
