HttpLimitZoneModule + Varnish (frontend)

[moon35]

Hello,

I'm having some troubles with the Module LimitZone. 
http://wiki.nginx.org/HttpLimitZoneModule

I want to limit simultaneous connections per client (IP) with
"limit_conn" but it doesn't work with Varnish-cache which is listening
to port 80 and NginX: 8080 

To do some tests I put limit_conn to 1 and I tried to download two files
from my server
If I write this on my browser adress bar :
 -> http://mydomain.tld:8080/file_to_dl.ext
it works of course (I got the error 503) but this :
 -> http://mydomain.tld/file_to_dl.ext
doesn't work: I can download more than 1 file.

I'm using php-fpm and $_SERVER['remote_addr'] give the right Client IP

Does anyone have a solution to my problem ? 
Thanks in advance.
