Just to give background http://farinspace.com/codeigniter-nginx-rewrite-rules/ seems to be exactly what I am trying to do, but it does not work. I get the index.php page when I go to http://mywebroot/folder_containing_index.php/

but when I go to http://mywebroot/folder_containing_index.php/url_information_to_pass_to_index.php it does not send the url information to index.php
