X-Accel-Redirect doen't work with php pages

[Daniele Melosi]

Hi all,

i tried using X-Accel-Redirect as described on this guide:
http://blog.kovyrin.net/2006/11/01/nginx-x-accel-redirect-php-rails/

If i use this conf:
daniele at lara:/var/www$ cat down.php
<?
// And redirect user to internal location
header("X-Accel-Redirect: /test.html");
?>

everything works fine but if i tried to call a php pages:
daniele at lara:/var/www$ cat down.php
<?
// And redirect user to internal location
header("X-Accel-Redirect: /test.php");
?>

with this error:
[error] 18345#0: *30 rewrite or internal redirection cycle while 
internal redirect to "/test.php" while reading response header from 
upstream, client: 192.168.251.27, server: localhost, request: "GET 
/down.php HTTP/1.1", upstream: "http://127.0.0.1:880/down.php"

this is my configuration:
server {
	listen   80;
	server_name  localhost;

	location / {
		root   /var/www/nginx-default;
		index  index.html index.htm;
	}

	location ~* .php$ {
		proxy_pass         http://127.0.0.1:880;
	        proxy_redirect     off;

         	proxy_set_header   Host             $host;
             	proxy_set_header   X-Real-IP        $remote_addr;
             	proxy_set_header   X-Forwarded-For 
$proxy_add_x_forwarded_for;

             	client_max_body_size       10m;
             	client_body_buffer_size    128k;

             	proxy_connect_timeout      90;
             	proxy_send_timeout         90;
             	proxy_read_timeout         90;

             	proxy_buffer_size          4k;
             	proxy_buffers              4 32k;
             	proxy_busy_buffers_size    64k;
             	proxy_temp_file_write_size 64k;
	}
