.htaccess help

[OniLink]

Hi,

I have the following .htaccess file in the public_html folder:

--
RewriteEngine on
RewriteCond %{HTTP_HOST} ^{(www.)?mydomain.com.au$}
RewriteCond %{REQUEST_URI} !^{/sites/saxon/}
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /sites/saxon/$1
RewriteCond %{HTTP_HOST} ^{(www.)?mydomain.com.au$}

RewriteRule ^(/)?$ sites/saxon/index.html [L]

It is basically making the "mydomain.com.au" set to "public_html/sites/saxon/index.php"

Anyway, I now want for "mydomain.com.au/admin" to set to "public_html/admin/index.php", but I'm not sure how to do it after doing the initial rewrite.

Does anyone know how I can do this?

Any help is appreciated,
~Oni.

I'm guessing that all of the files in admin should avoid redirection, right? In that case, after this line:

RewriteCond %{REQUEST_URI} !^/sites/saxon/

try putting this one:

RewriteCond %{REQUEST_URI} !^/admin

EDIT removed a slash.
