Thanks for the responses.
Looks like both of those will work; however, as I understand it the 'proper' way to do this involves the 301 / .htaccess redirect, as it should not affect your SE listings:

This is the code as it exists in the .htaccess now:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$ [NC]
RewriteRule (.*) index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
RewriteRule index\.html index.php [NC,R]
The last line is what should do it, however i think that something preceding this is causing the issue.
