Apache config stuff:
    # For branches
    RewriteCond %{HTTP_HOST} ^(.+)\.(.+)\.(.+)\.(.+)\.inside\.eseoh\.com$
    RewriteRule (.*) /var/www/%4.inside.eseoh.com/%3/%1/%2/$1

    # For trunks
    RewriteCond %{HTTP_HOST} ^(.+)\.(.+)\.(.+)\.inside\.eseoh\.com$
    RewriteRule (.*) /var/www/%3.inside.eseoh.com/%2/%1/$1


Goal:
When a URL is: http://at16.intranet.astoria-branches.vmnexus.inside.eseoh.com/ it should match the first rule

When a URL: is http://intranet.astoria_turkey-trunk.vmnexus.inside.eseoh.com/ it should match the second rule.
