Hello

I have recently moved my website from Litespeed to nginx. I had to change some lines in my PHP script to use x-sendfile function and because of it I also had to change my nginx config. Unfortunately, when I'm executing my PHP script, I receive 500 Internal Server Error. My error.log says:


2012/07/18 17:39:52 [error] 23510#0: *20011855 rewrite or internal redirection cycle while internal redirect to "/index.php", client: 31.175.62.69, server: modbase.pl, request: "GET [...]

I'm not sure what's causing this problem and how to fix it and I really need your help.

My nginx website's config:
server {
listen 80;
server_name modbase.pl;
server_name_in_redirect off;
client_max_body_size 1024m;
access_log /home/log/nginx/localhost.access_log;
error_log /home/log/nginx/localhost.error_log;
send_timeout 180;
root /home/modbase.pl/public_html;
index index.php;
# Support Clean (aka Search Engine Friendly) URLs
location / {
client_max_body_size 1024m;
try_files $uri $uri/ /index.php?q=$uri&$args;
proxy_read_timeout 120;
send_timeout 180;
autoindex on;
}

index index.php index.html index.htm default.html default.htm;
# deny running scripts inside writable directories
location ~* /(images|cache|media|logs|tmp)/.*\.(php|pl|py|jsp|asp|sh|cgi)$ {
return 403;
#error_page 403 /403_error.html;
}

location ~ .*.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_connect_timeout 320;

fastcgi_read_timeout 320;
client_max_body_size 1024m;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi_params;
send_timeout 180;
fastcgi_param SCRIPT_FILENAME /home/modbase.pl/public_html$fastcgi_script_name;
}

location /downloads {
internal;
}

# caching of files
location ~* \.(ico|pdf|flv)$ {
expires 1y;
}

location ~* \.(js|css|png|jpg|jpeg|gif|swf|xml|txt)$ {

}

}

My PHP script snippet that uses x-sendfile:

$filename_directoo = '/'.$cat_dir.'/'.$file_url;
header("X-Accel-Redirect:".$filename_directoo);
header('Content-Disposition: attachment; filename="'.$filename.'"');
