i have the following setup which uses nginx as proxy to an apache  
instance  
running prestashop, this works ok, but i get from time to time Error 310  
ERR\_TOO\_MANY\_REDIRECTS and i can’t figure out where this is coming from  
and  
i also get these error in the apache log:

```
[Sun Jun 09 18:57:01 2013] [error] [client xx.xx.xx.xx] client sent

```

HTTP/1.1 request without hostname (see RFC2616 section 14.23):  
/w00tw00t.at.ISC.SANS.DFind:)  
[Sun Jun 09 19:21:29 2013] [error] [client xx.xx.xx.xx] client sent  
HTTP/1.1 request without hostname (see RFC2616 section 14.23):  
/w00tw00t.at.ISC.SANS.DFind:)

here is my setup:

```

then in my /usr/local/etc/nginx/nginx.conf i have:

```
#user nobody;

            include custom/proxy_params;
            proxy_pass http://127.0.0.1:81;
    }
}

```

the `custom/prestashop_params` are as follows:

```
# cat custom/prestashop_params
rewrite "^/([a-z]{2})/js/(.+)$" /js/$2 last;
rewrite ^/([0-9])(\-[_a-zA-Z0-9-]*)?(-[0-9]+)?/.+\.jpg$

rewrite ^/images\_ie/?([^/]+).(jpe?g|png|gif)$  
/js/jquery/plugins/fancybox/images/$1.$2 last;

and `custom/proxy_params`:

```
# cat custom/proxy_params
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_buffers 16 128k;
proxy_busy_buffers_size 128k;
proxy_buffer_size 128k;
proxy_cache nginx-cache;
proxy_cache_valid 200 302 60m;
proxy_cache_valid 404 1m;
proxy_redirect off;

```

http.conf is setup to listen to port 81 and the vhost is:

```
<VirtualHost *:81>
    ServerAdmin removed_email_address@domain.invalid
    DocumentRoot /www/domain.tld/http/
    ServerName domain.tld
    <Directory "/www/domain.tld/http">
        Options Indexes FollowSymLinks
        AllowOverride All
        Order allow,deny
        Allow from all
    </Directory>
    ErrorLog /www/domain.tld/logs/error_log
    CustomLog /www/domain.tld/logs/access_log common
</VirtualHost>

```

i also have IPFW setup on my server and have opened both port 80 and 81  
but  
not sure this has anything to do with it.

is there a way to trace this, so that i can understand it better?  
perhaps  
the issue is the .htaccess in the /www/domain.tld/http root directory  
that  
is causing this!

and can this setup be made simpler, as i will have several prestashops  
instances running from this server with individual SSL certificates?

any advice much appreciated.
