Say I have a URL like this:

www.foo.website.com/some-page

Is it possible to rewrite the URL to this?

www.website.com/some-page?var=foo

I'm asking about a rewrite and not a redirect, so I'm wanting the first URL to stay in the address bar, but for the server to "get" the second URL. Also, as you can probably deduce, this needs to work for any subdomain, not just "foo."

I should add that this .htaccess file is also being used by WordPress and has the following code:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /~kbj/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /~kbj/index.php [L]
</IfModule>

Is what I'm asking possible to do?

If it is WP3 it has multi-site capabilities built in.

I'm not trying to make multiple WordPress sites, though.

Is what I asked possible? If so, does anyone know how to write the .htaccess code?

But that is EXACTLY what you ARE doing.

You want a sub-domain, which to all intents and purposes is an independent website, to resolve so a particular document located at a particular URI, or do you honestly think that every subdomain at wordpress.com is a seperate installation of Wordpress?
