Nginx Configuration: Symfony 2.1.2 (Development Mode)

symfony.conf

server {
	listen 80;
	server_name .symfony.dev;

	access_log /var/log/nginx/symfony.dev-access.log;
	error_log  /var/log/nginx/symfony.dev-error.log error;

	root /var/www/symfony.dev/web;
#	index app.php;
	index app_dev.php;

	try_files $uri $uri/ @rewrite;

	location @rewrite {
#		rewrite ^/(.*)$ /app.php/$1;
		rewrite ^/(.*)$ /app_dev.php/$1;
	}  

	location ~ \.php {
#		fastcgi_index app.php;
		fastcgi_index app_dev.php;

		fastcgi_pass unix:/usr/local/var/run/php-fpm.socket;

		include fastcgi_params;
		fastcgi_split_path_info ^(.+\.php)(/.+)$;
		fastcgi_param PATH_INFO $fastcgi_path_info;
		fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
		fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
	}

	location ~ /\.ht {
		deny all;
	}
}

Why are you using it:
rewrite ^/(.*)$ /app.php/$1;

if on htaccess has it:
RewriteRule ^(.*)$ app.php [QSA,L]

The apache aren't using the $1
