Subdomains pointing to a permalink URL

Question

I have Wordpress (v3.2.1) set up at domain.org.nz/wordpress with a number of pages set up as domain.org.nz/wordpress/services/example. I want to set up a subdomain, example.domain.org.nz to point to domain.org.nz/wordpress/services/example. When the subdomain is entered into the address bar, it (preferably) should stay as the subdomain (not a redirect). If there are any child pages of /example, the URL needs to appear as example.domain.org.nz/child. I have access to all Wordpress files, .htaccess, DNS settings etc but as I'm on a shared server, I don't have access to the httpd.conf

I know this is a similar question to Multiple Domain Names - One WP Install (non-Multisite) - Default Each Domain name to Category Archive Can I use the same method? If so what needs to be changed for that to work in my instance?

After almost a week of butting my head against this problem, any help is very much appreciated!!

Current .htaccess:

    # BEGIN WordPress  
    <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /wordpress/
    RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.org\.nz$
    RewriteRule ^(.*) http://domain.org.nz/wordpress/services/%1
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /wordpress/index.php [L]
    </IfModule>

    # END WordPress

Answer 1

Either try placing an index.php file inside your subdomain folder with the following code:

<?php
header("HTTP/1.1 301 Moved Permanently");
header("Status: 301 Moved Permanently");
header("Location: http://www.my-domain.com/my-permalink/");
?>

or use cPanel to setup/redirect the subdomain to any address you want.

Answer 2

First you have to configure your server (DNS + Apache) to let the subdomains point to the main site domain. Usually this does not require direct access to httpd.conf but can be configured in the hosting control panel (e.g. if using cPanel you may simply add subdomains (or a wildcard) pointing to the root folder of the site).

Then add a Rewrite Rule to your .htaccess in site's root, before the Wordpress rules (not tested):

RewriteEngine on
RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.org\.nz$
RewriteRule ^(.*) http://domain.org.nz/wordpress/services/%1
