I have the following in my .htaccess file:
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^api api.php [QSA,L]
Which I can browse to just fine - both /api
and something like /api/5
However, when I try to access the url via backbone I get a 404 error. Not really sure where to go on this one...
