Subject Re: [users@httpd] Need Help Configuring Virtual Hosts With DNS Aliases
Date Thu, 03 Jan 2013 00:15:33 GMT
You need only one VH really to handle both:

<VirtualHost *>
        ServerAdmin    devtoolsandcomponents@msx.bala.susq.com
        ServerName     sdlcdevbal832
        *ServerAlias    redmine redminetest*

        RewriteEngine On

        # Redirect all non-static requests to cluster for redmine
        # Redirect the rest to 127.0.0.1:4000
        RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
        RewriteCond %{HTTP_HOST} !^redminetest$
        RewriteRule ^/(.*)$ balancer://redminecluster%{REQUEST_URI}
[P,QSA,L]
        RewriteRule (.*) http://127.0.0.1:4000$1
</VirtualHost>
