I'm using JoomSEF 3.2.2. And I get a 404 NOT FOUND status on my component which is called through .htaccess redirection
In the profiles folder on my site where xml config files are stored I have an .htaccess with following lines
RewriteEngine On
RewriteRule ^(.*/data\.xml)$ /index.php?option=com_data_xml&format=raw&xml_path=$1 [L]

I am not using JoomSEF redirect but JoomSEF code is executed when accessing my component this way and it sets '404 NOT FOUND' http header. Can I disable JoomSEF execution in my component or somehow make it display 200 OK?
