rewrite or internal redirection cycle while internally redirecting to "/index.php"

[adambenayoun]

Hello everyone,
I'm having some issue with X-accel and I'd be happy if someone could look
over my configuration file and let me know what I did wrong.
I am basically running nginx/1.2.5 with php-fpm 5.3.3 on Centos 5.5

I am running an application that is served using Zend Framework from
/var/www/domain/html/http
I have many files available for download from
/var/www/domain/html/files/projects/$id/$file_name ($id is anything ranging
from 1-999 and $file_name is a zip file).

I want to basically serve the zip files using X-Accel and bypass php-fpm.

In the application when I check if the file can be served or not - I added
this: header("X-Accel-Redirect: " . $file); in order to serve it using
X-Accel.

I also added this location in my config to serve the zip files using nginx
        location /projects {
                internal;
                root /var/www/domain/html/files;
        }

The problem is I get a 500 error and when I look at the log file - this is
what I can spot:

[error] 10274#0: *25 rewrite or internal redirection cycle while internally
redirecting to "/index.php"
