Hi,  
I have a nginx frontend server with a mongrel backend.  
it all worked fine.

Then i used the ujs plugin and changed the following line in the  
nginx.conf

i changed this section:

```
        location ~*

```

^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|js|mov)$  
{  
client\_max\_body\_size 20M;  
root /var/rails\_apps/hozl/public;  
}

i removed the ‘js’ extension because otherwise nginx tries to serve all  
the javascript which now is partly generated by mongrel because of the  
ujs plugin

after this change all worked fine … on IE  
the problems begin with firefox.  
(mostly it is the other way around, i know :))

sometimes i can load a page quickly but very often all seems to freeze.  
firefox says "waiting for " and after a while i get a page  
looking like html source code like this:

HTTP/1.1 302 Moved TemporarilyServer: nginx/0.5.11

You are being [redirected](http://demo5.xwire.nl/patients/search).

my nginx.conf file looks like this:

# number of nginx workers

worker\_processes 6;

error\_log logs/error.log notice;  
pid logs/nginx.pid;

# Number of worker connections. 1024 is a good default

events {  
worker\_connections 1024;  
}

http {  
include conf/mime.types;

# no sendfile on OSX uncomment

                rewrite (.*) /index.html last;

            proxy_pass http://hozl2;
        }

        # rail caching: searching first for $action.html local pages
        location / {

            if (!-f $request_filename.html) {

            }
            rewrite (.*) $1.html last;
        }

        location ~ .html {

            proxy_redirect off;

            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For

```

$proxy\_add\_x\_forwarded\_for;  
}

```
}

```

}

i hope somebody knows where to look, cause i am lost here

thanks
