Hi,

this is a piece of zimbra’s nginx proxy default configuration:

http  
{  
…

```
upstream zimbra
{
        server mbs1.server.it:8080;

    zmauth;
}

# HTTP route lookup handlers
#
    zmroutehandlers 

```

mbs1.server.it:7072/service/extension/nginx-lookup;

```
zmroute_timeout 15000ms;

```

…  
}

I have the same needs: the HTTP servers upstream must change according  
to the value written inside the cookie zmauth.

Does an add-on exist?

Please help me,

thank you
