Problem with nginx in combination with ujs plugin and firefo

Rails
1

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.

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;
default_type application/octet-stream;

# no sendfile on OSX uncomment
# this if your on linux or bsd
sendfile  on;
tcp_nopush  on;
tcp_nodelay  off;

#keepalive_timeout  165;

upstream hozl2 {
server 127.0.0.1:8030;
server 127.0.0.1:8031;

}

server {

client_max_body_size 50M;
server_name hozl2;

    access_log  off;
    rewrite_log on;

        # / -> first search for local index.html then go to mongrel
        location ~ ^/$ {
client_max_body_size 20M;
            if (-f /index.html){
                rewrite (.*) /index.html last;
            }
            proxy_pass  http://hozl2;
        }

        # rail caching: searching first for $action.html local pages
        location / {
client_max_body_size 20M;
            if (!-f $request_filename.html) {
                proxy_pass  http://hozl2;
            }
            rewrite (.*) $1.html last;
        }

        # serve static files directly
        location ~ .html {
client_max_body_size 50M;
            root /var/rails_apps/hozl2/public;
        }

        location ~*

^.+.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp|rtf|mov)$
{
client_max_body_size 50M;
root /var/rails_apps/hozl2/public;
}

        # resend everything else to mongrel
        location / {
client_max_body_size 50M;
            proxy_pass  http://hozl2;
            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;
}

}

}

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

thanks
